Add support for overlay networking in older kernels.
Following were done to achieve this:
+ Create the vxlan network in host namespace.
+ This may create conflicts with other private
networks so check for conflicts and fail a
join if there is any conflict.
+ Add iptable based filtering to only allow
subnet bridges in the same network to forward
traffic while different network bridges will
not be able to forward b/w each other. Also
block traffic to overlay network originating
from the host itself.

- Added etcd integration test for overlay
- Added etcd integration test for multinode
with mock test driver suitable for circleci
- Added multinode tests for zookeeper
- Made the script smart enough to only start
data stores necessary for the requested suites

- With the selectively running a suite support
one can do the following to select which suite
of tests to run:
SUITES="simple multi" sudo -E make integration-tests
- Refactored and cleaned up some ununsed code in helpers.bash
- Added discover string parse function to parse discovery
string into provide and address

This commit adds a basic overlay network
connectivity integration test. By doing this
it adds the basic functions to form a crude
container to run the networking tests. The container
uses a busybox rootfs with network namespace and
/etc/hosts and /etc/resolv.conf generated by
libnetwork.

- Create a wrapper script to run intergation tests
so that setups and teardowns happen in more
optimal manner
- Add traps to cleanup containers on failure or
user interrupt
- Introduce basic multi-node integration tests
- Removed default network, default driver tests
as they may not be useful in the near future
