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.

Since libnetwork is going to provide createNetwork
notifications only once when the network is created
bridge network needs to save it's network state in
persistent store so that it becomes available even
after restart.

- Set bridge ipv4 address when bridge is present
- IPv6 changes for bridge
- Convert unit tests to the new model

Now that libkv supports concurrent access to boltdb, there is no point
in depending on timeout mechanism

Currently when docker exits ungracefully it may leave
dangling sandboxes which may hold onto precious network
resources. Added checkpoint state for sandboxes which
on boot up will be used to clean up the sandboxes and
network resources.
On bootup the remaining dangling state in the checkpoint
are read and cleaned up before accepting any new
network allocation requests.

This adds a new options configuration routine that the engine
can call in order to configure TLS for libnetworks KV store.

- libnetwork should reserve only the auxiliary
addresses which belong to the container
addresable pool. And should fail the network
creation if the aux addr does not belong to
the master pool.

Currently every `NewDatastore` creates a brand new
libkv store handle. This change attempts to share
the libkv store handle across various datastore handles
which share the same scope configuration. This enables
libnetwork and drivers to have different datastore handle
based on the same configuration but share the same
underlying libkv store handle.
This is mandatory for boltdb libkv backend because no two
clients can get exclusive access to boltdb file at the same
time. For other backends it just avoids the overhead of having
too many backend client instances

- Renamed netlabel prefixes to accomodate both global
and local store configs.
- Added a `private` marker.
- Skipping the data store configs for remote driver
so that external plugins don't get it as there is
no secure and sane way to coordinate providing
data store access to external plugins.

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.

specifically deals with multiple bridge networks

Remove the need for watching for IPAM data
structures and add multi store support code and
data reorganization to simplify address space
management.

Always on watching of networks and endpoints can
affect scalability of the cluster beyond a few nodes.
Remove pro active watching and watch only the objects
you are interested in.

Add local scope store caching support as
well as do some refactoring to make it datastore
scope aware and manage scope specific config.

Currently the default ipam implementation ignores the prefered ip if the
request is made on an existing sub-pool. The priority should be other
way around.
