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.

Previously hook expected data with a wrong type.
Full netns path is not included with the data
passed with the hook.
Fixes#829

- ... on ungraceful shutdown during network create
- Allow forceful deletion of network
- On network delete, first mark the network for deletion
- On controller creation, first forcely remove any network
that is marked for deletion.

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.

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.

Exposing osl package outside libnetwork is not neccessary and the
InterfaceStatistics anyways belong to the types package.

Replaced it with DisableBridgeCreation and it can be used ONLY in
a special case for docker0 bridge from docker, instead of calling it
from all other case.

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
Currently the driver configuration is pushed through a separate
api. This makes driver configuration possible at any arbitrary
time. This unncessarily complicates the driver implementation.
More importantly the driver does not get access to it's
configuration before it can do the handshake with libnetwork.
This make the internal drivers a little bit different to
external plugins which can get their configuration before the handshake
with libnetwork.
This PR attempts to fix that mismatch between internal drivers and
external plugins.

Currently the endpoint data model consists of multiple
interfaces per-endpoint. This seems to be an overkill
since there is no real use case for it. Removing it
to remove unnecessary complexity from the code.

This way we won't vendor test related functions in docker anymore.
It also moves netns related functions to a new ns package to be able to
call the ns init function in tests. I think this also helps with the
overall package isolation.

- Convinience API which detaches the sandbox from
all endpoints, resets and reapply config options,
setup discovery files, reattach to the endpoints.
No change to the osl sandbox in use.
