Mahmood Ali 6c8e329819 test that stopped alloc jobs aren't modified 
When an alloc is stopped, test that we don't update the job found in
alloc with new job  that is no longer relevent for this alloc.

Mahmood Ali 6bdbeed319 set node.StatusUpdatedAt in raft 
Fix a case where `node.StatusUpdatedAt` was manipulated directly in
memory.

This ensures that StatusUpdatedAt is set in raft layer, and ensures that
the field is updated when node drain/eligibility is updated too.

Fix bug in plan applier introduced in PR-5602 
This fixes a bug in the state store during plan apply. When
denormalizing preempted allocations it incorrectly set the preemptor's
job during the update. This eventually causes a panic downstream in the
client. Added a test assertion that failed before and passes after this fix

Mahmood Ali 9c0a15f3ce Run job deregistering in a single transaction 
Fixes https://github.com/hashicorp/nomad/issues/4299

Upon investigating this case further, we determined the issue to be a race between applying `JobBatchDeregisterRequest` fsm operation and processing job-deregister evals.

Processing job-deregister evals should wait until the FSM log message finishes applying, by using the snapshot index.  However, with `JobBatchDeregister`, any single individual job deregistering was applied accidentally incremented the snapshot index and resulted into processing job-deregister evals.  When a Nomad server receives an eval for a job in the batch that is yet to be deleted, we accidentally re-run it depending on the state of allocation.

This change ensures that we delete deregister all of the jobs and inserts all evals in a single transactions, thus blocking processing related evals until deregistering complete.

Alex Dadgar 1c31970464 Fix multiple tgs with progress deadline handling 
Fix an issue in which the deployment watcher would fail the deployment
based on the earliest progress deadline of the deployment regardless of
if the task group has finished.

Further fix an issue where the blocked eval optimization would make it
so no evals were created to progress the deployment. To reproduce this
issue, prior to this commit, you can create a job with two task groups.
The first group has count 1 and resources such that it can not be
placed. The second group has count 3, max_parallel=1, and can be placed.
Run this first and then update the second group to do a deployment. It
will place the first of three, but never progress since there exists a
blocked eval. However, that doesn't capture the fact that there are two
groups being deployed.
