* docker: disable driver when running as non-root on cgroups v2 hosts
This PR modifies the docker driver to behave like exec when being run
as a non-root user on a host machine with cgroups v2 enabled. Because
of how cpu resources are managed by the Nomad client, the nomad agent
must be run as root to manage docker-created cgroups.
* cl: update cl
This change introduces the Task API: a portable way for tasks to access Nomad's HTTP API. This particular implementation uses a Unix Domain Socket and, unlike the agent's HTTP API, always requires authentication even if ACLs are disabled.
This PR contains the core feature and tests but followup work is required for the following TODO items:
- Docs - might do in a followup since dynamic node metadata / task api / workload id all need to interlink
- Unit tests for auth middleware
- Caching for auth middleware
- Rate limiting on negative lookups for auth middleware

Many of the functions in the `utils.go` file are specific to a particular
scheduler, and very few of them have guards (or even names) that help avoid
misuse with features specific to a given scheduler type. Move these
functions (and their tests) into files specific to their scheduler type without
any functionality changes to make it clear which bits go with what.

Service jobs should have unique allocation Names, derived from the
Job.ID. System jobs do not have unique allocation Names because the index is
intended to indicated the instance out of a desired count size. Because system
jobs do not have an explicit count but the results are based on the targeted
nodes, the index is less informative and this was intentionally omitted from the
original design.
Update docs to make it clear that NOMAD_ALLOC_INDEX is always zero for
system/sysbatch jobs
Validate that `volume.per_alloc` is incompatible with system/sysbatch jobs.
System and sysbatch jobs always have a `NOMAD_ALLOC_INDEX` of 0. So
interpolation via `per_alloc` will not work as soon as there's more than one
allocation placed. Validate against this on job submission.
* largely a doc-ification of this commit message:
d47678074b
this doesn't spell out all the possible failure modes,
but should be a good starting point for folks.
* connect: add doc link to envoy bootstrap error
* add Unwrap() to RecoverableError
mainly for easier testing
Add `identity` jobspec block to expose workload identity tokens to tasks.

If a deployment fails, the `deployment status` command can get a nil deployment
when it checks for a rollback deployment if there isn't one (or at least not one
at the time of the query). Fix the panic.

The ACL token decoding was not correctly handling time duration
syntax such as "1h" which forced people to use the nanosecond
representation via the HTTP API.
The change adds an unmarshal function which allows this syntax to
be used, along with other styles correctly.
Prior to 2409f72 the code compared the modification index of a job to itself. Afterwards, the code compared the creation index of the job to itself. In either case there should never be a case of re-parenting of allocs causing the evaluation to trivially always result in false, which leads to unreclaimable memory.
Prior to this change allocations and evaluations for batch jobs were never garbage collected until the batch job was explicitly stopped. The new `batch_eval_gc_threshold` server configuration controls how often they are collected. The default threshold is `24h`.
* docker: set force=true on remove image to handle images referenced by multiple tags
This PR changes our call of docker client RemoveImage() to RemoveImageExtended with
the Force=true option set. This fixes a bug where an image referenced by more than
one tag could never be garbage collected by Nomad. The Force option only applies to
stopped containers; it does not affect running workloads.
* docker: add note about image_delay and multiple tags
While you can use any string value for a variable Item's key name
using characters that are outside of the set [unicode.Letter,
unicode.Number,`_`] will require the `index` function for direct
access.
* Ensure infra_image gets proper label used for reconciliation
Currently infra containers are not cleaned up as part of the dangling container
cleanup routine. The reason is that Nomad checks if a container is a Nomad owned
container by verifying the existence of the: `com.hashicorp.nomad.alloc_id` label.
Ensure we set this label on the infra container as well.
* fix unit test
* changelog: add entry
