This fix tries to fix logrus formatting by removing `f` from
`logrus.[Error|Warn|Debug|Fatal|Panic|Info]f` when formatting string
is not present.
Also fix import name to use original project name 'logrus' instead of
'log'

When stale delete notifications are received, we still need to make sure
to purge sandbox neighbor cache because these stale deletes are most
typically out of order delete notifications and if an add for the
peermac was received before the delete of the old peermac,vtep pair then
we process that and replace the kernel state but the old neighbor state
in the sandbox cache remains. That needs to be purged when we finally
get the out of order delete notification.

Fixed certain spurious overlay errors which were not errors at all but
showing up everytime service tasks are started in the engine.
Also added a check to make sure a delete is valid by checking the
incoming endpoint id wih the one in peerdb just to make sure if the
delete from gossip is not stale.

Currently overlay driver requires a k/v store to allocate a vxlan id and
add an entry in k/v store for network->vxlanIDs binding. But the overlay
driver should be able to work without a k/v store provided libnetwork
can pass along the vxlanIDs needed for the network, rather than the
driver managing it themselves. Modified the driver to work with vxlanIDs
passed down by libnetwork.
Also made changes in the driver to make use of the gossip layer
available in libnetwork if available.

If we use peerMap as value, then we copy its mutex on
`pMap = d.peerDb.mp[nid]` and lock entirely different mutexes every
time.

With the new Discovery model, join can happen even before serf is
initliazed. It could also happen due to misconfiguration of
--cluster-advertise. The local endpoint join must succeed and later when
the serf initializes and joins the cluster, it will push the local db to
the cluster.

- 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

When you start a container after some other container has already
been started in the same network, the current container will have
an fdb which points to a wrong vtep to reach the already started
container. This makes the network connectivity to not work. The root
cause of the issue is because of golang does variable capture by
reference in closures and so we cannot use the return values from
range iterators directly. It needs to be copied to a locally scoped
variable and then use that copy as a capture variable in the closure.

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.
