9c3ce6b6dc persist shared ports during inplace updates (#9736)
AllocatedSharedResources were not being copied over to the new
allocation struct the scheduler makes during inplace updates. This
caused downstream issues after the plan was applied, namely the shared
ports were dropped causing issues with service
registration/deregistration.

3826e23047 scheduler: enable upgrade path for bridge network finger print
This PR enables users of Nomad < 0.12 to upgrade to Nomad 0.12
and beyond. Nomad 0.12 introduced a network fingerprinter for
bridge networks, which is a contstraint checked for if bridge
network is being used. If users upgrade servers first as is
recommended, suddenly no clients running older versions of Nomad
will satisfy the bridge network resource constraint. Instead,
this change only enforces the constraint if the Nomad client
version is also >= 0.12.

Closes #8423

a55f46e9ba api: add field filters to /v1/{allocations,nodes}
Fixes #9017

The ?resources=true query parameter includes resources in the object
stub listings. Specifically:

- For `/v1/nodes?resources=true` both the `NodeResources` and
  `ReservedResources` field are included.
- For `/v1/allocations?resources=true` the `AllocatedResources` field is
  included.

The ?task_states=false query parameter removes TaskStates from
/v1/allocations responses. (By default TaskStates are included.)

7cff2de942 csi: allow more than 1 writer claim for multi-writer mode (#9040)
Fixes a bug where CSI volumes with the `MULTI_NODE_MULTI_WRITER` access mode
were using the same logic as `MULTI_NODE_SINGLE_WRITER` to determine whether
the volume had writer claims available for scheduling.

Extends CSI claim endpoint test to exercise multi-reader and make sure `WriteFreeClaims`
is exercised for multi-writer in feasibility test.

37cd0eced3 consul/connect: trigger update as necessary on connect changes
This PR fixes a long standing bug where submitting jobs with changes
to connect services would not trigger updates as expected. Previously,
service blocks were not considered as sources of destructive updates
since they could be synced with consul non-destructively. With Connect,
task group services that have changes to their connect block or to
the service port should be destructive, since the network plumbing of
the alloc is going to need updating.

Fixes #8596 #7991

Non-destructive half in #7192

The change was intended to fix a case where a canary alloc may fail to
be rescheduled if all the other allocs fail as well (e.g. if all allocs
happen to be placed on a node that died).  However, it introduced some
unintended side-effects.

Reverting the change for now and will investigate further.

6f6a93b262 Handle migration of non-deployment jobs
This handles the case where a job when from no-deployment to deployment
with canaries.

Consider a case where a `max_parallel=0` job is submitted as version 0,
then an update is submitted with `max_parallel=1, canary=1` as verion 1.
In this case, we will have 1 canary alloc, and all remaining allocs will
be version 0.  Until the deployment is promoted, we ought to replace the
canaries with version 0 job (which isn't associated with a deployment).

5720266c91 Respect alloc job version for lost/failed allocs
This change fixes a bug where lost/failed allocations are replaced by
allocations with the latest versions, even if the version hasn't been
promoted yet.

Now, when generating a plan for lost/failed allocations, the scheduler
first checks if the current deployment is in Canary stage, and if so, it
ensures that any lost/failed allocations is replaced one with the latest
promoted version instead.

6ed0f4e564 scheduler: DesiredCanaries can be set on every pass safely
The reconcile loop sets `DeploymentState.DesiredCanaries` only on the first
pass through the loop and if the job is not paused/pending. In MRD,
deployments will make one pass though the loop while "pending", and were not
ever getting `DesiredCanaries` set. We can't set it in the initial
`DeploymentState` constructor because the first pass through setting up
canaries expects it's not there yet. However, this value is static for a given
version of a job because it's coming from the update stanza, so it's safe to
re-assign the value on subsequent passes.

5cb11b78d1 refactor: make it clear where we're accessing dstate
The field name `Deployment.TaskGroups` contains a map of `DeploymentState`,
which makes it a little harder to follow state updates when combined with
inconsistent naming conventions, particularly when we also have the state
store or actual `TaskGroup`s in scope. This changeset changes all uses to
`dstate` so as not to be confused with actual TaskGroups.

3b52b39c50 mrd: reconcile should treat pending deployments as paused (#8446)
If a job update includes a task group that has no changes, those allocations
have their version bumped in-place. The ends up triggering an eval from
`deploymentwatcher` when it verifies their health. Although this eval is a
no-op, we were only treating pending deployments the same as paused when
the deployment was a new MRD. This means that any eval after the initial one
will kick off the deployment, and that caused pending deployments to "jump
the queue" and run ahead of schedule, breaking MRD invariants and resulting in
a state with all regions blocked.

This behavior can be replicated even in the case of job updates with no
in-place updates by patching `deploymentwatcher` to inject a spurious no-op
eval. This changeset fixes the behavior by treating pending deployments the
same as paused in all cases in the reconciler.

3703489702 MRD: all regions should start pending (#8433)
Deployments should wait until kicked off by `Job.Register` so that we can
assert that all regions have a scheduled deployment before starting any
region. This changeset includes the OSS fixes to support the ENT work.

`IsMultiregionStarter` has no more callers in OSS, so remove it here.

114881c2aa reconcile should not overwrite unblocking state (#8349)
Pre-0.12.0 beta, a deployment was considered "complete" if it was
successful. But with MRD we have "blocked" and "unblocking" states as well. We
did not consider the case where a concurrent alloc health status update
triggers a `Compute` call on a deployment that's moved from "blocked" to
"unblocking" (it's a small window), which caused an extra pass thru the
`nextRegion` logic in `deploymentwatcher` and triggered an error when later
transitioning to "successful".

This changeset makes sure we don't overwrite that status.

1916051580 multiregion: initial deploymentPaused must match start condition (#8215)
In #8209 we fixed the `max_parallel` stanza for multiregion by introducing the
`IsMultiregionStarter` check, but didn't apply it to the earlier place its
required. The result is that deployments start but don't place allocations.

5a068e6005 multiregion: all regions start in running if no max_parallel (#8209)
If `max_parallel` is not set, all regions should begin in a `running` state
rather than a `pending` state. Otherwise the first region is set to `running`
and then all the remaining regions once it enters `blocked. That behavior is
technically correct in that we have at most `max_parallel` regions running,
but definitely not what a user expects.

abd3a2b846 multiregion: use pending instead of paused
The `paused` state is used as an operator safety mechanism, so that they can
debug a deployment or halt one that's causing a wider failure. By using the
`paused` state as the first state of a multiregion deployment, we risked
resuming an intentionally operator-paused deployment because of activity in a
peer region.

This changeset replaces the use of the `paused` state with a `pending` state,
and provides a `Deployment.Run` internal RPC to replace the use of the
`Deployment.Pause` (resume) RPC we were using in `deploymentwatcher`.
