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.

Add Cleanup method to Driver interface
2017-01-20 13:02:14 -08:00

Michael Schurter 4d081490e6 Add Cleanup method to Driver interface
Cleanup can be used for cleaning up resources created by drivers to run
a task. Initially the Docker driver is the only user (to remove
downloaded images).

Alex Dadgar 2be221d664 Don't retrieve Driver Stats if unsupported
This PR makes us only try to collect stats once if the Driver doesn't
support collecting stats.

Michael Schurter 770ed703d0 Add Driver.Prestart method
The Driver.Prestart method currently does very little but lays the
foundation for where lifecycle plugins can interleave execution _after_
task environment setup but _before_ the task starts.

Currently Prestart does two things:

* Any driver specific task environment building
* Download Docker images

This change also attaches a TaskEvent emitter to Drivers, so they can
emit events during task initialization.
