By removing the need to clear the default gateway during sbJoin and
sbLeave to account for other bridge network, the default-gw endpoint
will stay with the container, it will also help retain the container
property.

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.

Compile the dnet tool for Linux (x86, amd64 and arm)
and Windows (x86 and amd64)
- Moved installation of dependencies into `Dockerfile.build`
- Remove `start-services` from Makefile
- That's the responsibility of Docker or build environment
- Removed utils depending on `netlink` from `netutils/utils.go`
Unable to add `make cross` to CircleCI just yet as there are some
issues to solve that are unrelated to this PR
Also fix `.gitignore` which was not updated after changing the build
image name in #667

Added IT cases for external connectivity check for bridge
and overlay networks, both initially and after a restart.

Added an IT case for checking proper /etc/hosts
handling in the overlay network. This also to see
if there are any stale entries in the /etc/hosts

A local endpoint is known to the watch database only
during Join. But the same endpoint can be known to the
watch database as remote endpoint well before the Join
because a CreateEndpoint updates the endpoint to the store.
So on Join when you come to know that this is indeed a
local endpoint remove it from remote endpoint list and add it
to local endpoint list.

- 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

Currently integration test is a bit flaky because of
variability in the dnet bootup time. Fixed it to wait for
dnet to come up before performing any tests.

Added restart test for default network so that we can test
bridge network persistence. Also added changes to dnet to
delete the default network if it is present.

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.

1. Don't save localscope endpoints to localstore for now.
2. Add common function updateToStore/deleteFromStore to store KVObjects.
3. Merge `getNetworksFromGlobalStore` and `getNetworksFromLocalStore`
4. Add `n.isGlobalScoped` before `n.watchEndpoints` in `addNetwork`
5. Fix integration-tests
6. Fix test failure in drivers/remote/driver_test.go
7. Restore network to store if deleteNework failed
- 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

- So test will not fail because container is already there
Prefer this to re-use the containers as it would contain
states from last run
- A stale consul or dnet container condition will happen
in case the previous integ test run aborted
