drivers/docker: add support for STOPSIGNAL

This fixes a bug where Nomad overrides a Dockerfile's STOPSIGNAL with
the default kill_signal (SIGTERM).

This adds a check for kill_signal. If it's not set, it calls
StopContainer instead of Signal, which uses STOPSIGNAL if it's
specified. If both kill_signal and STOPSIGNAL are set, Nomad tries to
stop the container with kill_signal first, before then calling
StopContainer.

Fixes #9989

Follow up to memory oversubscription - expose an env-var to indicate when memory oversubscription is enabled and what the limit is.

This will be helpful for setting hints to app for memory management.

* style(downloads): adds releaseCandidate style

* refactor(downloads): use mktg-logos asset

This commit ensures Nomad captures the task code more reliably even when the task is killed. This issue affect to `raw_exec` driver, as noted in https://github.com/hashicorp/nomad/issues/10430 .

We fix this issue by ensuring that the TaskRunner only calls `driver.WaitTask` once. The TaskRunner monitors the completion of the task by calling `driver.WaitTask` which should return the task exit code on completion. However, it also could return a "context canceled" error if the agent/executor is shutdown.

Previously, when a task is to be stopped, the killTask path makes two WaitTask calls, and the second returns "context canceled" occasionally because of a "race" in task shutting down and depending on driver, and how fast it shuts down after task completes.

By having a single WaitTask call and consistently waiting for the task, we ensure we capture the exit code reliably before the executor is shutdown or the contexts expired.

I opted to change the TaskRunner implementation to avoid changing the driver interface or requiring 3rd party drivers to update.

Additionally, the PR ensures that attempts to kill the task terminate when the task "naturally" dies. Without this change, if the task dies at the right moment, the `killTask` call may retry to kill an already-dead task for up to 5 minutes before giving up.

Updates website banner for Nomad 1.1

This closes #10489. It adds `dependentKeyCompat` to the allocation getter so it works
as expected as a dependent key for the `tracker` computed property, as described here:
https://guides.emberjs.com/release/upgrading/current-edition/tracked-properties/#toc_backwards-compatibility

demo: apply hclfmt to ceph files

The error returned from the stdlib's `exec` package is always a message with
the exit code of the exec'd process, not any error message that process might
have given us. This results in opaque failures for the Nomad user. Cast to an
`ExitError` so that we can access the output from stderr.

connect: use deterministic injected dynamic exposed port label

This changeset expands on the existing demonstration we had for Ceph by
showing volume creation. It includes a demo setup for Ceph on Vagrant so that
you don't need a whole Ceph cluster to try it out.
