Switch from global-redis-check for the example job's service name to
redis-cache. The former name is really confusing and someone finally
called us out on it:

Also specifically mention that the `service.name` parameter is what is
advertised in Consul.
Our Docker network plugin autodetection code was erroneously treating
Window's default network `nat` as a plugin and defaulting to it instead
of the host.
Fixes#3218
Caught some typos. Made units separate from the numbers 1GHz -> 1 GHz
after talking to Nick about questions of style (this has the side effect of making future spell checking easier).
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.
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.
