DriverContext: Add the TaskGroup and the Job name

Adding this fields to the DriverContext object, will allow us to pass

An use case for this, will be to emit tagged metrics in the drivers,
which contain all relevant information:
- Job

Fix interpolation bug with service/check updates

Previously if only an interpolated variable used in a service or check

new variable, so nothing appeared to have changed.

Handle leader task being dead in RestoreState
...
Fixes the panic mentioned in
https://github.com/hashicorp/nomad/issues/3420#issuecomment-341666932
While a leader task dying serially stops all follower tasks, the
synchronizing of state is asynchrnous. Nomad can shutdown before all
follower tasks have updated their state to dead thus saving the state
necessary to hit this panic: *have a non-terminal alloc with a dead
leader.*
The actual fix is a simple nil check to not assume non-terminal allocs
leader's have a TaskRunner.

RestartDelay isn't needed as checks are re-added on restarts
...
@dadgar made the excellent observation in #3105 that TaskRunner removes
and re-registers checks on restarts. This means checkWatcher doesn't
need to do *any* internal restart tracking. Individual checks can just
remove themselves and be re-added when the task restarts.

Template emits events explaining why it is blocked
...
This PR does the following:
* Adds a mechanism to emit events in the TaskRunner
* Vendors a new version of Consul-Template that allows extraction of
missing dependencies
* Adds logic to our consul_template.go to determine missing events and
emit them in a batched fashion.
* Refactors the consul_template code to split the run method and take in
a config struct rather than many parameters.

Ideally DriverNetwork would be fully populated in Driver.Prestart, but
Docker doesn't assign the container's IP until you start the container.
However, it's important to setup the port env vars before calling
Driver.Start, so Prestart should populate that.
