* [QT-602] Run `proxy` and `agent` test scenarios (#23176)
Update our `proxy` and `agent` scenarios to support new variants and
perform baseline verification and their scenario specific verification.
We integrate these updated scenarios into the pipeline by adding them
to artifact samples.
We've also improved the reliability of the `autopilot` and `replication`
scenarios by refactoring our IP address gathering. Previously, we'd ask
vault for the primary IP address and use some Terraform logic to determine
followers. The leader IP address gathering script was also implicitly
responsible for ensuring that a found leader was within a given group of
hosts, and thus waiting for a given cluster to have a leader, and also for
doing some arithmetic and outputting `replication` specific output data.
We've broken these responsibilities into individual modules, improved their
error messages, and fixed various races and bugs, including:
* Fix a race between creating the file audit device and installing and starting
vault in the `replication` scenario.
* Fix how we determine our leader and follower IP addresses. We now query
vault instead of a prior implementation that inferred the followers and sometimes
did not allow all nodes to be an expected leader.
* Fix a bug where we'd always always fail on the first wrong condition
in the `vault_verify_performance_replication` module.
We also performed some maintenance tasks on Enos scenarios byupdating our
references from `oss` to `ce` to handle the naming and license changes. We
also enabled `shellcheck` linting for enos module scripts.
* Rename `oss` to `ce` for license and naming changes.
* Convert template enos scripts to scripts that take environment
variables.
* Add `shellcheck` linting for enos module scripts.
* Add additional `backend` and `seal` support to `proxy` and `agent`
scenarios.
* Update scenarios to include all baseline verification.
* Add `proxy` and `agent` scenarios to artifact samples.
* Remove IP address verification from the `vault_get_cluster_ips`
modules and implement a new `vault_wait_for_leader` module.
* Determine follower IP addresses by querying vault in the
`vault_get_cluster_ips` module.
* Move replication specific behavior out of the `vault_get_cluster_ips`
module and into it's own `replication_data` module.
* Extend initial version support for the `upgrade` and `autopilot`
scenarios.
We also discovered an issue with undo_logs that has been described in
the VAULT-20259. As such, we've disabled the undo_logs check until
it has been fixed.
* actions: fix actionlint error and linting logic (#23305)

Rather than assuming a short sleep will work, we instead wait until netcat is listening of the socket. We've also configured the netcat listener to persist after the first connection, which allows Vault and us to check the connection without the process closing.
As we implemented this we also ran into AWS issues in us-east-1 and us-west-2, so we've changed our deploy regions until those issues are resolved.

Replace our prior implementation of Enos test groups with the new Enos
sampling feature. With this feature we're able to describe which
scenarios and variant combinations are valid for a given artifact and
allow enos to create a valid sample field (a matrix of all compatible
scenarios) and take an observation (select some to run) for us. This
ensures that every valid scenario and variant combination will
now be a candidate for testing in the pipeline. See QT-504[0] for further
details on the Enos sampling capabilities.
Our prior implementation only tested the amd64 and arm64 zip artifacts,
as well as the Docker container. We now include the following new artifacts
in the test matrix:
* CE Amd64 Debian package
* CE Amd64 RPM package
* CE Arm64 Debian package
* CE Arm64 RPM package
Each artifact includes a sample definition for both pre-merge/post-merge
(build) and release testing.
Changes:
* Remove the hand crafted `enos-run-matrices` ci matrix targets and replace
them with per-artifact samples.
* Use enos sampling to generate different sample groups on all pull
requests.
* Update the enos scenario matrices to handle HSM and FIPS packages.
* Simplify enos scenarios by using shared globals instead of
cargo-culted locals.
Note: This will require coordination with vault-enterprise to ensure a
smooth migration to the new system. Integrating new scenarios or
modifying existing scenarios/variants should be much smoother after this
initial migration.

Add an updated `target_ec2_instances` module that is capable of
dynamically splitting target instances over subnet/az's that are
compatible with the AMI architecture and the associated instance type
for the architecture. Use the `target_ec2_instances` module where
necessary. Ensure that `raft` storage scenarios don't provision
unnecessary infrastructure with a new `target_ec2_shim` module.
After a lot of trial, the state of Ec2 spot instance capacity, their
associated APIs, and current support for different fleet types in AWS
Terraform provider, have proven to make using spot instances for
scenario targets too unreliable.
The current state of each method:
* `target_ec2_fleet`: unusable due to the fact that the `instant` type
does not guarantee fulfillment of either `spot` or `on-demand`
instance request types. The module does support both `on-demand` and
`spot` request types and is capable of bidding across a maximum of
four availability zones, which makes it an attractive choice if the
`instant` type would always fulfill requests. Perhaps a `request` type
with `wait_for_fulfillment` option like `aws_spot_fleet_request` would
make it more viable for future consideration.
* `target_ec2_spot_fleet`: more reliable if bidding for target instances
that have capacity in the chosen zone. Issues in the AWS provider
prevent us from bidding across multiple zones succesfully. Over the
last 2-3 months target capacity for the instance types we'd prefer to
use has dropped dramatically and the price is near-or-at on-demand.
The volatility for nearly no cost savings means we should put this
option on the shelf for now.
* `target_ec2_instances`: the most reliable method we've got. It is now
capable of automatically determing which subnets and availability
zones to provision targets in and has been updated to be usable for
both Vault and Consul targets. By default we use the cheapest medium
instance types that we've found are reliable to test vault.
* Update .gitignore
* enos/modules/create_vpc: create a subnet for every availability zone
* enos/modules/target_ec2_fleet: bid across the maximum of four
availability zones for targets
* enos/modules/target_ec2_spot_fleet: attempt to make the spot fleet bid
across more availability zones for targets
* enos/modules/target_ec2_instances: create module to use
ec2:RunInstances for scenario targets
* enos/modules/target_ec2_shim: create shim module to satisfy the
target module interface
* enos/scenarios: use target_ec2_shim for backend targets on raft
storage scenarios
* enos/modules/az_finder: remove unsed module

Determine the allocation pool size for the spot fleet by the allocation
strategy. This allows us to ensure a consistent attribute plan during
re-runs which avoid rebuilding the target fleets.

The security groups that allow access to remote machines in Enos
scenarios have been configured to only allow port 22 (SSH) from the
public IP address of machine executing the Enos scenario. To achieve
this we previously utilized the `enos_environment.public_ip_address`
attribute. Sometime in mid March we started seeing sporadic SSH i/o
timeout errors when attempting to execute Enos resources against SSH
transport targets. We've only ever seen this when communicating from
Azure hosted runners to AWS hosted machines.
While testing we were able to confirm that in some cases the public IP
address resolved using DNS over UDP4 to Google and OpenDNS name servers
did not match what was resolved when using the HTTPS/TCP IP address
service hosted by AWS. The Enos data source was implemented in a way
that we'd attempt resolution of a single name server and only attempt
resolving from the next if previous name server could not get a result.
We'd then allow-list that single IP address. That's a problem if we can
resolve two different public IP addresses depending our endpoint address.
This change utlizes the new `enos_environment.public_ip_addresses`
attribute and subsequent behavior change. Now the data source will
attempt to resolve our public IP address via name servers hosted by
Google, OpenDNS, Cloudflare, and AWS. We then return a unique set of
these IP addresses and allow-list all of them in our security group. It
is our hope that this resolves these i/o timeout errors that seem like
they're caused by the security group black-holing our attempted access
because the IP we resolved does not match what we're actually exiting
with.

The previous strategy for provisioning infrastructure targets was to use
the cheapest instances that could reliably perform as Vault cluster
nodes. With this change we introduce a new model for target node
infrastructure. We've replaced on-demand instances for a spot
fleet. While the spot price fluctuates based on dynamic pricing,
capacity, region, instance type, and platform, cost savings for our
most common combinations range between 20-70%.
This change only includes spot fleet targets for Vault clusters.
We'll be updating our Consul backend bidding in another PR.
* Create a new `vault_cluster` module that handles installation,
configuration, initializing, and unsealing Vault clusters.
* Create a `target_ec2_instances` module that can provision a group of
instances on-demand.
* Create a `target_ec2_spot_fleet` module that can bid on a fleet of
spot instances.
* Extend every Enos scenario to utilize the spot fleet target acquisition
strategy and the `vault_cluster` module.
* Update our Enos CI modules to handle both the `aws-nuke` permissions
and also the privileges to provision spot fleets.
* Only use us-east-1 and us-west-2 in our scenario matrices as costs are
lower than us-west-1.
