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.

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.

Make sure to always explicitly set namespace for all
kernel bound network operations irrespective of whether
the operation is performed in init namespace or a user
defined namespace. This already happens for user defined
netns. But doesn't happen for initial netns that libnetwork
runs in.

- Maps 1 to 1 with container's networking stack
- It holds container's specific nw options which
before were incorrectly owned by Endpoint.
- Sandbox creation no longer coupled with Endpoint Join,
sandbox and endpoint have now separate lifecycle.
- LeaveAll naturally replaced by Sandbox.Delete
- some pkg and file renaming in order to have clear
mapping between structure name and entity ("sandbox")
- Revisited hosts and resolv.conf handling
- Removed from JoinInfo interface capability of setting hosts and resolv.conf paths
- Changed etchosts.Build() to first write the search domains and then the nameservers
