There were some unconditional debug logging in serf.
Removed them and made then go through logrus writers
based on what error level the log string contains.

With the recently introduced docker discovery, the self node discovery
notification can reach the overlay driver after the remote node
discovery notification. In scenarios such as 2 node setup, it seems more
likely. In those scenarios, the serfJoin is not triggered and hence the
neighborship is not formed between the 2 nodes.
The fix is to retain the knowledge of the neighbor and reuse it
immediately after the serfInit is done. Since we do the serfJoin just
once, there is no harm in changing the neighIP to a new value even if it
is not used.

- Maps 1 to 1 with container's networking stack
- It holds container's specific nw options which
before were incorrectly owned by Endpoint.
- Sandbox creation no longer coupled with Endpoint Join,
sandbox and endpoint have now separate lifecycle.
- LeaveAll naturally replaced by Sandbox.Delete
- some pkg and file renaming in order to have clear
mapping between structure name and entity ("sandbox")
- Revisited hosts and resolv.conf handling
- Removed from JoinInfo interface capability of setting hosts and resolv.conf paths
- Changed etchosts.Build() to first write the search domains and then the nameservers

This commit brings in the first implementation of
overlay driver which makes use of vxlan tunneling
protocol to create logical networks across multiple
hosts.
This is very much alpha code and should be used for
demo and testing purposes only.
