This PR allows to configure the discovery path using the
--discovery-opt flag (with "kv.path=path/to/nodes"). We
can point to "docker/nodes" and use the docker discovery.
If docker instances are advertising to the cluster using
the `--cluster-advertise` flag, the swarm join command
becomes unnecessary.

Docker daemon uses kv-store as the host-discovery backend.
Discovery module tracks the liveness of a node through a simple
keepalive mechanism. The keepalive mechanism depends on every
node performing heartbeat by registering itself with the discovery
module (via KV-Store Put operation). And for every Put operation,
the discovery module in all other nodes will receive a Watch
notification. That keeps the node alive.
Any node that fails to register itself within the TTL timer is
considered dead and removed from the discovery database.
The default timer (heartbeat = 20 seconds & ttl = 60 seconds)
works fine for small clusters. But for large clusters, these
default timers are extremely aggressive and that causes high CPU
& most of the processing is spent managing the node discovery
and that impacts normal daemon operation.
Hence we need a way to make the discovery ttl and heartbeat
configurable. As the cluster size grows, the user can change
these timers to make sure the daemon scales.

Our implementation of systemd cgroups is mixture of systemd api and
plain filesystem api. It's hard to keep it up to date with systemd and
it already contains some nasty bugs with new versions. Ideally it should
be replaced with some daemon flag which will allow to set parent systemd
slice.

Use `pkg/discovery` to provide nodes discovery between daemon instances.
The functionality is driven by two different command-line flags: the
experimental `--cluster-store` (previously `--kv-store`) and
`--cluster-advertise`. It can be used in two ways by interested
components:
1. Externally by calling the `/info` API and examining the cluster store
field. The `pkg/discovery` package can then be used to hit the same
endpoint and watch for appearing or disappearing nodes. That is the
method that will for example be used by Swarm.
2. Internally by using the `Daemon.discoveryWatcher` instance. That is
the method that will for example be used by libnetwork.
