Michael Schurter 3b15db1ac4 Ignore Consul deregister errors on executors
Errors here only occur if Consul is not running when Nomad is restarted.

Errors here are only an issue if:
 * Consul is being used but is down or misbehaving
 * The executor is old (<0.6)
 * The task has services
 * The services hit a pre-0.6 consul.Syncer bug

If all of those conditions are met the pre-0.6 bugs will persist for
this task until Nomad is restarted.

Alex Dadgar bddedd7aba Don't deepcopy job when retrieving copy of Alloc
This PR removes deepcopying of the job attached to the allocation in the
alloc runner. This operation is called very often so removing reflect
from the code path and the potentially large number of mallocs need to
create a job reduced memory and cpu pressure.

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.

Michael Schurter 547d5a81b4 Chown files when copying into chroot
Fixes #2552

Not needed when hardlinking. Only adds Linux support but other OS's may
be easy.

Alex Dadgar 61f4a2dac6 Sync allocation state before waiting for a destroy
This change ensures that the client syncs allocation state with the
servers before entering its wait loop for the allocation to be
destroyed.
