Michael Schurter 67a7b0eac9 Don't panic in container list/remove/inspect race
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.

Michael Schurter b9bfb84b53 Implement DriverNetwork and Service.AddressMode
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.

Michael Schurter e204a287ed 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.

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.

Evan Phoenix 8864a506aa Disable the syslog logging system on Docker For Mac
The syslog logging system depends on the ability for a unix socket to be
accessed by the docker daemon in the $TMPDIR of the host. This doesn't
work on Docker For Mac because the docker daemon is running inside a VM,
and while /tmp is accessible, the filesystem used to share them doesn't
support unix socket files, and thus it doesn't work.

Jan-Hendrik Lendholt a26a501120 Fixed a bug when giving in another logging driver than syslog.
Before this commit, if the Logging config did not contain a logging option "syslog-address", it would definitely insert this option.
If then, you decide to take another logdriver than syslog, docker would fail because it received a wrong log option for the selected driver.
Now, nomad will only insert the syslog address in a hard way if there are no logging options at all - this way it keeps the default nomad settings.

Jan-Hendrik Lendholt 6c7cbe5fcb Added support to mount host folders into container. For example if you don't want to bake certificates into the container, you can mount them into the directory directly.
Furthermore, I added support for volumes-from.

Currently, there is no support to move the data from one container to another, hence: If a container spawns on another host, it is very likely, that the data will not be found.
