We no longer intend to release 32-bit builds for any platform. We'd previously
removed the builds for i386 on both Linux and Windows, but never got around to
removing the ARM builds. Add a note about this deprecation in the release notes
for 1.8.x.
Update the documentation for the `spread` block:
* Make it clear that the default behavior within a given job when the `spread`
block is omitted is to spread out allocs among feasible nodes.
* Describe the difference between the `spread` block and `spread` scheduler
algorithm.
* Add warnings about the performance impact of using `spread` and how to
mitigate it.
Our documentation for the `node drain` command doesn't include a treatment of
batch jobs, which are not migrated. The user is left to piece this behavior
together from the `migrate` documentation and the tutorial. Instead, let's
explicitly list the behaviors per job type.

This allows users to set a custom value of attempts that will be made to purge
an existing (not running) container if one is found during task creation.

Users can override the default sidecar task for Connect workloads. This sidecar
task might need access to certificate stores on the host. Allow adding the
`volume_mount` block to the sidecar task override.
Also fixes a bug where `volume_mount` blocks would not appear in plan diff
outputs.

The ACL docs have a section explaining that some parts of the UI need slightly
wider read permissions than expected. These docs should include that you need
`plugin:read` to look at CSI volume pages in the UI.

* drivers/raw_exec: enable setting cgroup override values
This PR enables configuration of cgroup override values on the `raw_exec`
task driver. WARNING: setting cgroup override values eliminates any
gauruntee Nomad can make about resource availability for *any* task on
the client node.
For cgroup v2 systems, set a single unified cgroup path using `cgroup_v2_override`.
The path may be either absolute or relative to the cgroup root.
config {
cgroup_v2_override = "custom.slice/app.scope"
}
or
config {
cgroup_v2_override = "/sys/fs/cgroup/custom.slice/app.scope"
}
For cgroup v1 systems, set a per-controller path for each controller using
`cgroup_v1_override`. The path(s) may be either absolute or relative to
the controller root.
config {
cgroup_v1_override = {
"pids": "custom/app",
"cpuset": "custom/app",
}
}
or
config {
cgroup_v1_override = {
"pids": "/sys/fs/cgroup/pids/custom/app",
"cpuset": "/sys/fs/cgroup/cpuset/custom/app",
}
}
* drivers/rawexec: ensure only one of v1/v2 cgroup override is set
* drivers/raw_exec: executor should error if setting cgroup does not work
* drivers/raw_exec: create cgroups in raw_exec tests
* drivers/raw_exec: ensure we fail to start if custom cgroup set and non-root
* move custom cgroup func into shared file

When setting up auth methods for Consul and Vault in production environments, we
can typically assume that the CA certificate for the JWKS endpoint will be in
the host certificate store (as part of the usual configuration management
cluster admins needs to do). But for quick demos with `-dev` agents, this won't
be the case.
Add a `-jwks-ca-file` parameter to the setup commands so that we can use this
tool to quickly setup WI with `-dev` agents running TLS.
