During incident response, operators may find that automated processes
elsewhere in the organization can be generating new workloads on Nomad
clusters that are unable to handle the workload. This changeset adds a
field to the `SchedulerConfiguration` API that causes all job
registration calls to be rejected unless the request has a management
ACL token.

The `consul.client_auto_join` configuration block tells the Nomad
client whether to use Consul service discovery to find Nomad
servers. By default it is set to `true`, but contrary to the
documentation it was only respected during the initial client
registration. If a client missed a heartbeat, failed a
`Node.UpdateStatus` RPC, or if there was no Nomad leader, the client
would fallback to Consul even if `client_auto_join` was set to
`false`. This changeset returns early from the client's trigger for
Consul discovery if the `client_auto_join` field is set to `false`.
Give ourselves some room for extension in the UI configuration block
by naming the field `ui_url`, which will let us have an `api_url`.
Fix the template path to ensure we're getting the right value from the
API.
When GetPolicy is called within the scaling handler, the index
table was being used to populate the reply index irregardless of
whether the policy was found or not. This change fixes that
behaviour so that the policy modify index is used when the policy
lookup is successful.
The `TestHTTPServer_Limits_Error` test never starts the agent so it
had an incomplete configuration, which caused panics in the test. Fix
the configuration.
The PR #11555 had a branch name like `f-ui-*` which caused CI to skip
the unit tests over the HTTP handler setup, so this wasn't caught in
PR review.
In the system scheduler, if a subset of clients are filtered by class,
we hit a code path where the `AllocMetric` has been copied, but the
`Copy` method does not instantiate the various maps. This leads to an
assignment to a nil map. This changeset ensures that the maps are
non-nil before continuing.
The `Copy` method relies on functions in the `helper` package that all
return nil slices or maps when passed zero-length inputs. This
changeset to fix the panic bug intentionally defers updating those
functions because it'll have potential impact on memory usage. See
https://github.com/hashicorp/nomad/issues/11564 for more details.

As of VirtualBox 6.1.28, host-only networks are restricted to
`192.168.56.0/21` by default, so spinning up the Vagrant boxes with
secondary networks fail with an error `E_ACCESSDENIED`.
Update the IP configuration of the Vagrant boxes to fall within the
allowed range so that we don't need to ask developers from the
community to make VirtualBox configuration updates outside of their
normal Vagrant use.
This change modifies the Nomad job register and deregister RPCs to
accept an updated option set which includes eval priority. This
param is optional and override the use of the job priority to set
the eval priority.
In order to ensure all evaluations as a result of the request use
the same eval priority, the priority is shared to the
allocReconciler and deploymentWatcher. This creates a new
distinction between eval priority and job priority.
The Nomad agent HTTP API has been modified to allow setting the
eval priority on job update and delete. To keep consistency with
the current v1 API, job update accepts this as a payload param;
job delete accepts this as a query param.
Any user supplied value is validated within the agent HTTP handler
removing the need to pass invalid requests to the server.
The register and deregister opts functions now all for setting
the eval priority on requests.
The change includes a small change to the DeregisterOpts function
which handles nil opts. This brings the function inline with the
RegisterOpts.
