This PR fixes:
* An issue in which a node-drain that contains a complete batch alloc
would cause a replacement
* An issue in which allocations with the same name during a scale
down/stop event wouldn't be properly stopped.
* An issue in which batch allocations from previous job versions may not
have been stopped properly.

This PR fixes a scheduling race condition in which the plan results from
one invocation of the scheduler were not being considered by the next
since the Worker was not waiting for the correct index.

This PR sorts the output of the endpoint since its results are used as
part of Consul checks to avoid the value changing unnecessarily.

This PR removes locking around commonly accessed node attributes that do
not need to be locked. The locking could cause nodes to TTL as the
heartbeat code path was acquiring a lock that could be held for an
excessively long time. An example of this is when Vault is inaccessible,
since the fingerprint is run with a lock held but the Vault
fingerprinter makes the API calls with a large timeout.

This PR fixes:
* UUID lookup with hyphens and odd length. The math was wrong. There is
now a test that ranges over all possible values.
* Fixes an unreported issue that could be hit when a job has more than 4
hyphens in it as UUID lookup doesn't allow that.
