The test is sadly quite complicated and peeks into things (logmon's
reattach config) AR doesn't normally have access to.
However, I couldn't find another way of asserting logmon got cleaned up
without resorting to smaller unit tests. Smaller unit tests risk
re-implementing dependencies in an unrealistic way, so I opted for an
ugly integration test.
Consider currently dequeued Evaluation's ModifyIndex when determining
its WaitIndex. Normally the Evaluation itself would already be in the
state store snapshot used to determine the WaitIndex. However, since the FSM
applies Raft messages to the state store concurrently with Dequeueing,
it's possible the currently dequeued Evaluation won't yet exist in the
state store snapshot used by JobsForEval.
This can be solved by always considering the current eval's modify index
and using it if it is greater than all of the evals returned by the
state store.
This commit is a significant change. TR.Run is now always executed, even
for terminal allocations. This was changed to allow TR.Run to cleanup
(run stop hooks) if a handle was recovered.
This is intended to handle the case of Nomad receiving a
DesiredStatus=Stop allocation update, persisting it, but crashing before
stopping AR/TR.
The commit also renames task runner hook data as it was very easy to
accidently set state on Requests instead of Responses using the old
field names.
strings.Replace call with n=0 argument makes no sense
as it will do nothing. Probably -1 is intended.

Upgrade e2e tests are failing and we haven't had bandwith to fix yet.
Having them fail makes it easy for us to miss other failures and
regressions.
As such, skip the upgrade e2e tests until we fix them.
Port some integration tests of driver fingerprinting.
Some tests (e.g. `TestFingerprintManager_Run_DriversInBlacklist`) have
been subsituted by more isolated tests in
`client/pluginmanager/drivermanager/manager_test.go`
This code chooses to be conservative as opposed to optimal: when failing
to reattach to logmon simply return a recoverable error instead of
immediately trying to restart logmon.
The recoverable error will cause the task's restart policy to be
applied and a new logmon will be launched upon restart.
Trying to do the optimal approach of simply starting a new logmon
requires error string comparison and should be tested against a task
actively logging to assert the behavior (are writes blocked? dropped?).
This commit causes the docker driver to return undetected before it
first establishes a connection to the docker daemon.
This fixes a bug where hosts without docker installed would return as
unhealthy, rather than undetected.
