Michael Schurter e204a287ed Refactor Consul Syncer into new ServiceClient 
Fixes #2478 #2474 #1995 #2294

The new client only handles agent and task service advertisement. Server
discovery is mostly unchanged.

The Nomad client agent now handles all Consul operations instead of the
executor handling task related operations. When upgrading from an
earlier version of Nomad existing executors will be told to deregister
from Consul so that the Nomad agent can re-register the task's services
and checks.

Drivers - other than qemu - now support an Exec method for executing
abritrary commands in a task's environment. This is used to implement
script checks.

Interfaces are used extensively to avoid interacting with Consul in
tests that don't assert any Consul related behavior.

Alex Dadgar 6bee23047a Fix variable capture and add tests 
This PR fixes token revocation and adds tests to make sure it is
working. The 0.5.6 RC1's token revocation does not work becasue the
token's value is captured at the instantiation of the deferred
stoprenewal statement rather than its exectution.

Alex Dadgar d1645f47b1 Stop Vault token renew on task exit 
This PR fixes an oversight in which the client would attempt to renew a
token even after the task exits.

This PR fixes an issue in which the reference count on a Docker image

Michael Schurter 0e6c564406 Improve artifact download error message 
Fixes #2289

Unfortunately took more RecoverableError hijinx than I would have liked.
There might be a better way.

Alex Dadgar fa853c9696 Fix two issues during client restore state 
This PR fixes two issues:

1) A close of a nil stopCollection channel when restoring and prestart
fails. The failure will cause the killCh to be triggered which will
close collection before it has been initialized.

2) Fixes a deadlock in which the handleWaitCh is never triggered since
it is not initialized when there is an error in prestart and the killCh
is triggered.

Both fixes are by maintaining the loop invariant that the two channels
are valid after there is a handle.

Michael Schurter 37e7e7a3e5 Fix upgrade path for created resources 
This *might* be a fix for #2295 -- I've been unable to reproduce the
bug. However, this guard seems wise regardless. I should never be
overwriting an intialized created resources with a nil.
