Enables other subsystems to watch actions for a plugin(s).
This will be used specifically for implementing plugins on swarm where a
swarm controller needs to watch the state of a plugin.

This code currently passes a random manager address when creating a new
Node. This doesn't really make sense - we should only pass a join
address on the initial join, or when retrying that join. An upcoming
change to swarmkit will pay attention to JoinAddr significant when a
node is already part of a cluster, so passing in the random value needs
to be avoided.

This commit in conjunction with a libnetwork side commit,
cleans up the libnetwork SetClusterProvider logic interaction.
The previous code was inducing libnetwork to spawn several go
routines that were racing between each other during the agent
init and close.
A test got added to verify that back to back swarm init and leave
are properly processed and not raise crashes

This new flag will allow the configuration of an interface that
can be used for data path traffic to be isolated from control
plane traffic. This flag is simply percolated down to libnetwork
and will be used by all the global scope drivers (today overlay)
Negative test added for invalid flag arguments

The agent sometimes calls into libnetwork code that in turn calls
(*Cluster).IsAgent and (*Cluster).IsManager. These can cause the
node shutdown process to time out, since they wait for a lock that is
held by Cleanup.
It turns out c.mu doesn't need to be held while calling Stop. Holding
controlMutex is sufficient. Also, (*nodeRunner).Stop must release
nodeRunner's mu during the node shutdown process, otherwise the same
call into Cluster would be blocked on this lock instead.

This is necessary for swarmkit to support cluster wide plugins, such as
globally scoped network plugins.

This fix tries to address the issue raised in 24596 where it was not
possible to join as manager only (`--availability=drain`).
This fix adds a new flag `--availability` to `swarm join`.
Related documentation has been updated.
An integration test has been added.
NOTE: Additional pull request for swarmkit and engine-api will
be created separately.
This fix fixes 24596.
