82ea86fb6f Track whether Consul has ever been seen 
Need a way to squelch Consul operation errors on shutdown. If it's never
been seen don't log errors about deregs failing.

bb45b95bc4 Allow tuning of heartbeat ttls 
This PR allows tuning of heartbeat TTLs. An example of very aggressive
settings is as follows:

```
server {
  heartbeat_grace = "1s"
  min_heartbeat_ttl = "1s"
  max_heartbeats_per_second = 200.0
}
```

More than gc_max_allocs may be running on a node, but terminal allocs
will be garbage collected to try to keep the total number below the
limit.

10cb924b2c 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.

701537e9c5 Limit parallelism during garbage collection 
This PR introduces a parallelism limit during garbage collection. This
is used to avoid large resource usage spikes if garbage collecting many
allocations at once.

4e7587de17 Choose safer default advertise address 
* -dev mode defaults bind & advertise to localhost
* Normal mode defaults bind to 0.0.0.0 & advertise to the resolved
  hostname. If the hostname resolves to localhost it will refuse to
  start and advertise must be manually set.

c86a07d834 Separate agent configuration into its own pages 
I apologize in advance for the rather long PR, but unfortunately there
is not an easy way to break this up into smaller chunks. This separates
the agent configuration into smaller, more consumable pieces just like
the job specification.
