Some operators use very long group/task `shutdown_delay` settings to
safely drain network connections to their workloads after service
deregistration. But during incident response, they may want to cause
that drain to be skipped so they can quickly shed load.
Provide a `-no-shutdown-delay` flag on the `nomad alloc stop` and
`nomad job stop` commands that bypasses the delay. This sets a new
desired transition state on the affected allocations that the
allocation/task runner will identify during pre-kill on the client.
Note (as documented here) that using this flag will almost always
result in failed inbound network connections for workloads as the
tasks will exit before clients receive updated service discovery
information and won't be gracefully drained.
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.
This PR adds the common OSS changes for adding support for Consul Namespaces,
which is going to be a Nomad Enterprise feature. There is no new functionality
provided by this changeset and hopefully no new bugs.
The initial implementation of global job stop for MRD looped over all the
regions in the CLI for expedience. This changeset includes the OSS parts of
moving this into the RPC layer so that API consumers don't have to implement
this logic themselves.

In multiregion deployments when ACLs are enabled, the deploymentwatcher needs
an appropriately scoped ACL token with the same `submit-job` rights as the
user who submitted it. The token will already be replicated, so store the
accessor ID so that it can be retrieved by the leader.
Integration points for multiregion jobs to be registered in the enterprise
version of Nomad:
* hook in `Job.Register` for enterprise to send job to peer regions
* remove monitoring from `nomad job run` and `nomad job stop` for multiregion jobs
Allow a `/v1/jobs?all_namespaces=true` to list all jobs across all
namespaces. The returned list is to contain a `Namespace` field
indicating the job namespace.
If ACL is enabled, the request token needs to be a management token or
have `namespace:list-jobs` capability on all existing namespaces.
This change provides an initial pass at setting up the configuration necessary to
enable use of Connect with Consul ACLs. Operators will be able to pass in a Consul
Token through `-consul-token` or `$CONSUL_TOKEN` in the `job run` and `job revert`
commands (similar to Vault tokens).
These values are not actually used yet in this changeset.
Jobs can be created with user-provided IDs containing any character
except spaces. The jobId needs to be escaped when used in a request
path, otherwise jobs created with names such as "why?" can't be managed
after they are created.
