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
* Parse Docker mounts correctly
This PR fixes the parsing of Docker mounts and adds testing to ensure no
regressions.

Yet another bug caused by overwriting container and then trying to
reference container.ID in the err handling block. Did a quick audit of
docker.go and it seems to be the last offender. See #2804 for previous
bug.
Fixes#2802
While it's hard to reproduce the theoretical race is:
1. This goroutine calls ListContainers()
2. Another goroutine removes a container X
3. This goroutine attempts to InspectContainer(X)
However, this bug could be hit in the much simpler case of
InspectContainer() timing out.
In those cases an error is returned and the old code attempted to wrap
the error with the now-nil container.ID. Storing the container ID fixes
that panic.
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.

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.
