This patch updates all dependencies to match what is
used in moby/moby. Making the dependencies match
what is used in that repository makes sure we test
with the same version as libnetwork is later built
with in moby.
This also gets rid of some temporary forks that were
needed during the migration of Sirupsen/logrus to
sirupsen/logrus.

This change cleans up the SetClusterProvider method.
Swarm calls the SetClusterProvider to pass to libnetwork the pointer
of the provider from which libnetwork can fetch all the information to
initialize the internal agent.
The method can be and is called multiple times passing the same value,
with the previous logic that was erroneusly spawning multiple go routines that
were making possiblea race between an agentInit and an agentClose.
The new logic aims to disallow it by checking for the provider passed and
ensuring that if the provider is already present there is nothing to do because
there is already an active go routine that is ready to process cluster events.
Moreover a patch on moby side takes care of clearing up the Cluster Events
dispacthing using only 1 channel to handle all the events types.
This will also guarantee in order event handling because now all the events are
piped into one single channel.

Change in the provider interface to let the provider

During configuration in SWARM mode is now possible to pass an additional
parameter --data-path-addr <ip|interface>.
The information is going to be used to configure which is the interface
that is going to be used for the data path for global scope drivers.
Up to now the only driver really using this extra parameter is the
overlay driver.

This fix tries to address the issue raised in:
https://github.com/docker/docker/issues/26341
where multiple addresses in a bridge may cause `--fixed-cidr` to
not have the correct addresses.
The issue is that `netutils.ElectInterfaceAddresses(bridgeName)`
only returns the first IPv4 address.
This fix changes `ElectInterfaceAddresses()` and `addresses()`
so that all IPv4 addresses are returned. This will allow the
possibility of selectively choose the address needed.

If user provided a non-zero listen address, honor that and bind only to
that address. Right now it is not honored and we always bind to all ip
addresses in the host.

With this change, all the auto-detection of the addresses are removed
from libnetwork and the caller takes the responsibilty to have a proper
advertise-addr in various scenarios (including externally facing public
advertise-addr with an internal facing private listen-addr)

Currently the libnetwork function `NewNetwork` does not allow
caller to pass a network ID and it is always generated internally.
This is sufficient for engine use. But it doesn't satisfy the needs
of libnetwork being used as an independent library in programs other
than the engine. This enhancement is one of the many needed to
facilitate a generic libnetwork.

Currently ipam/ipamutils has a bunch of dependencies
in osl and netlink which makes the ipam/ipamutils harder
to use independently with other applications. This PR
modularizes ipam/ipamutils into a standalone package
with no OS level dependencies.

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.

There are multiple goals of introducing test driver plugin
- Need a driver which can be configured to simulate
different driver behaviors
- For pure libnetwork multi-host integration testing
a test driver configured for global scope can be used
without trying to use a real driver like overlay
which comes with it's own dependencies which can't
be satisfied all enviroments(I am looking at you
circleci)
This PR also makes all test cases that we have so far to be run
in circleci without any skipping needed.
