In Consul 1.15.0, the Delete Token API was changed so as to return an error when
deleting a non-existent ACL token. This means that if Nomad successfully deletes
the token but fails to persist that fact, it will get stuck trying to delete a
non-existent token forever.
Update the token deletion function to ignore "not found" errors and treat them
as successful deletions.

* cni: ensure to setup CNI addresses in deterministic order
Currently as commented in the code the go-cni library returns an unordered map
of interfaces. In cases where there are multiple CNI interfaces being created this
creates a problem with service registration and healthchecking because the first
address in the map is being used.
The use case we have where this is an issue is that we run CNI with the macvlan
plugin to isolate workloads, but they still need to be able to access the host on
a static address to be able to perform local resolving and hit host services like
the Consul agent API. To make this work there are 2 options, you either add a
macvlan interface on the host with an assigned address for each VLAN you have or
you create an additional veth bridged interface in the container namespace.
We chose the latter option through a custom CNI plugin but the ordering issue
leaves us with incorrect service registration.
* Updates after feedback
* First check for the CNIResult interfaces length, if it's zero we don't need to proceed
at all.
* Use sorted interfaces list for the address fallback scenario as well.
* Remove "found" log message logic, when an address isn't found an error is returned stating
the allocation could not be configured as an address was missing from the CNIResult. If we
still need a Warn message then we can add it to the condition that returns the error if no
address could be found instead of using the "found" bool logic.
this is basically to avoid Fear/Uncertainty/Doubt
the github action actions/setup-go
(and, with a different chache key, hashicorp/setup-golang)
caches both GOMODCACHE (go source files), which is good,
and GOCACHE (build outputs), which *might* be bad,
if the cache was built on an OS with an older glibc
than we want to support. from `go help cache`:
> [...] the build cache does not detect changes to
> C libraries imported with cgo.
so in enterprise we can use Vault for secrets,
without merge conflicts from oss->ent.
also:
* use hashicorp/setup-golang
* setup-js for self-hosted runners
they don't come with yarn, nor chrome,
and might not always match node version.
Service discovery or mesh network systems consuming the Nomad event stream or API need to know the CNI assigned IP for the allocation. This data is returned by the underlying Nomad API but isn't mapped in the response struct.

The requirements for client-to-server and client-to-client topologies are not
well-documented in the production install requirements docs. Document that
clients make connections to servers (and not the other way around), and that
clients don't need to communicate with each other (with some exceptions).

Update the revision used by the docker action. This should always reflect the commit that's being built as this may differ from the default <github.sha> that the workflow was invoked at.
Goes with https://github.com/hashicorp/actions-docker-build/pull/59 - and should not be merged until this PR is merged and a new version of the action is cut.
* drivers/docker: refactor use of clients in docker driver
This PR refactors how we manage the two underlying clients used by the
docker driver for communicating with the docker daemon. We keep two clients
- one with a hard-coded timeout that applies to all operations no matter
what, intended for use with short lived / async calls to docker. The other
has no timeout and is the responsibility of the caller to set a context
that will ensure the call eventually terminates.
The use of these two clients has been confusing and mistakes were made
in a number of places where calls were making use of the wrong client.
This PR makes it so that a user must explicitly call a function to get
the client that makes sense for that use case.

* cr: followup items
Given a deployment that has a `progress_deadline`, if a task group runs
out of reschedule attempts, allow it to fail at this time instead of
waiting until the `progress_deadline` is reached.

* CSS alignment and spacing for job status panel
* Only fade the count, not the legend icon, when count is 0
* Unrounded version corners
* changelog
* css has to only remove border radius when count is present
* Seed stabilization for services test
* Try consolidating the testfixes from before
* Total test isolation and bonus logs
* Drop the isolation but keep the logs
* Remove bonus logging
This PR refactors some old PID isolation tests to make use of the e2e/v3
packages. Should be quite a bit easier to read. Adds 'alloc exec' capability
to the jobs3 package.
In #17354 we made client updates prioritized to reduce client-to-server
traffic. When the client has no previously-acknowledged update we assume that
the update is of typical priority; although we don't know that for sure in
practice an allocation will never become healthy quickly enough that the first
update we send is the update saying the alloc is healthy.
But that doesn't account for allocations that quickly fail in an unrecoverable
way because of allocrunner hook failures, and it'd be nice to be able to send
those failure states to the server more quickly. This changeset does so and adds
some extra comments on reasoning behind priority.
If you use `nomad node drain -force`, the drain deadline is set to -1ns. If you
have not prevented system and CSI node plugin allocations from being drained
with `-ignore-system`, they will be immediately drained as well. This is
typically not safe for CSI node plugins.
Also fix some broken links.
