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.

Introducing a new approach to testing Vault artifacts before merge
and after merge/notorization/signing. Rather than run a few static
scenarios across the artifacts, we now have the ability to run a
pseudo random sample of scenarios across many different build artifacts.
We've added 20 possible scenarios for the AMD64 and ARM64 binary
bundles, which we've broken into five test groups. On any given push to
a pull request branch, we will now choose a random test group and
execute its corresponding scenarios against the resulting build
artifacts. This gives us greater test coverage but lets us split the
verification across many different pull requests.
The post-merge release testing pipeline behaves in a similar fashion,
however, the artifacts that we use for testing have been notarized and
signed prior to testing. We've also reduce the number of groups so that
we run more scenarios after merge to a release branch.
We intend to take what we've learned building this in Github Actions and
roll it into an easier to use feature that is native to Enos. Until then,
we'll have to manually add scenarios to each matrix file and manually
number the test group. It's important to note that Github requires every
matrix to include at least one vector, so every artifact that is being
tested must include a single scenario in order for all workflows to pass
and thus satisfy branch merge requirements.
* Add support for different artifact types to enos-run
* Add support for different runner type to enos-run
* Add arm64 scenarios to build matrix
* Expand build matrices to include different variants
* Update Consul versions in Enos scenarios and matrices
* Refactor enos-run environment
* Add minimum version filtering support to enos-run. This allows us to
automatically exclude scenarios that require a more recent version of
Vault
* Add maximum version filtering support to enos-run. This allows us to
automatically exclude scenarios that require an older version of
Vault
* Fix Node 12 deprecation warnings
* Rename enos-verify-stable to enos-release-testing-oss
* Convert artifactory matrix into enos-release-testing-oss matrices
* Add all Vault editions to Enos scenario matrices
* Fix verify version with complex Vault edition metadata
* Rename the crt-builder to ci-helper
* Add more version helpers to ci-helper and Makefile
* Update CODEOWNERS for quality team
* Add support for filtering matrices by group and version constraints
* Add support for pseudo random test scenario execution

Previously we'd pass the matrix variant to the backend cluster module which is currently unsupported by the consul module. Instead we'll always pass the ubuntu/amd64 AMI ID to the consul backend module.
This should resolve the enos-verify-stable matrix failures here https://github.com/hashicorp/vault/actions/runs/3448137968/jobs/5754873688#step:11:191

Here we make the following major changes:
* Centralize CRT builder logic into a script utility so that we can share the
logic for building artifacts in CI or locally.
* Simplify the build workflow by calling a reusable workflow many times
instead of repeating the contents.
* Create a workflow that validates whether or not the build workflow and all
child workflows have succeeded to allow for merge protection.
Motivation
* We need branch requirements for the build workflow and all subsequent
integration tests (QT-353)
* We need to ensure that the Enos local builder works (QT-558)
* Debugging build failures can be difficult because one has to hand craft the
steps to recreate the build
* Merge conflicts between Vault OSS and Vault ENT build workflows are quite
painful. As the build workflow must be the same file and name we'll reduce
what is contained in each that is unique. Implementations of building
will be unique per edition so we don't have to worry about conflict
resolution.
* Since we're going to be touching the build workflow to do the first two
items we might as well try and improve those other issues at the same time
to reduce the overhead of backports and conflicts.
Considerations
* Build logic for Vault OSS and Vault ENT differs
* The Enos local builder was duplicating a lot of what we did in the CRT build
workflow
* Version and other artifact metadata has been an issue before. Debugging it
has been tedious and error prone.
* The build workflow is full of brittle copy and paste that is hard to
understand, especially for all of the release editions in Vault Enterprise
* Branch check requirements for workflows are incredibly painful to use for
workflows that are dynamic or change often. The required workflows have to be
configured in Github settings by administrators. They would also prevent us
from having simple docs PRs since required integration workflows always have
to run to satisfy branch requirements.
* Doormat credentials requirements that are coming will require us to modify
which event types trigger workflows. This changes those ahead of time since
we're doing so much to build workflow. The only noticeable impact will be
that the build workflow no longer runs on pushes to non-main or release
branches. In order to test other branches it requires a workflow_dispatch
from the Actions tab or a pull request.
Solutions
* Centralize the logic that determines build metadata and creates releasable
Vault artifacts. Instead of cargo-culting logic multiple times in the build
workflow and the Enos local modules, we now have a crt-builder script which
determines build metadata and also handles building the UI, Vault, and the
package bundle. There are make targets for all of the available sub-commands.
Now what we use in the pipeline is the same thing as the local builder, and
it can be executed locally by developers. The crt-builder script works in OSS
and Enterprise so we will never have to deal with them being divergent or with
special casing things in the build workflow.
* Refactor the bulk of the Vault building into a reusable workflow that we can
call multiple times. This allows us to define Vault builds in a much simpler
manner and makes resolving merge conflicts much easier.
* Rather than trying to maintain a list and manually configure the branch check
requirements for build, we'll trigger a single workflow that uses the github
event system to determine if the build workflow (all of the sub-workflows
included) have passed. We'll then create branch restrictions on that single
workflow down the line.
