Alex Dadgar 4ecebe7d8c Proper reference counting through task restarts
This PR fixes an issue in which the reference count on a Docker image
would become inflated through task restarts.

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).

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.

Michael Schurter f430203505 Put lxc support behind a flag
Since lxc support requires linking to a C lib at compile and runtime
I'm putting it behind a build flag to avoid forcing all nomad users to
install liblxc (lxc-dev for development).
