After moving libnetwork to this repo, we need to update all the import
paths for libnetwork to point to docker/docker/libnetwork instead of
docker/libnetwork.
This change implements that.

Default gateways truncate the endpoint name to 12 characters. This can
make network endpoints ambiguous especially for load-balancing sandboxes
for networks with lenghty names (such as with our prefixes). Address
this by detecting an overflow in the sanbox name length and instead
opting to name the gateway endpoint "gateway_<id>" which should never
collide.

- Currently if the join fails, the gw endpoint becomes
stale and stays connected to the gw network.
- Also fix sbJoin to do the cleanup in case
setupDefaultGW() fails

- Restoring original behavior where on disconnect
from overlay network (only connected network), it also
disconnects from default gw network.
- On sandbox delete, the leave and delete of each
endpoint is performed, regardless of whether the endpoint
is the gw network endpoint. This endpoint is already
automatically removed in endpoint.sbLeave()
- Also do not let internal network dictate container does
not need external connectivity. Before this fix, if a container
was connected to an overlay and an internal network, it may not
get attached to the default gw network.

automatically removed in endpoint.sbLeave() by
sb.clearDefaultGW() when the sandbox is marked for
deletion.

- needDefaultGw() takes now into account whether the sandbox
is marked for deletion

Stale sandbox and endpoints are cleaned up during controller init.
Since we reuse the exact same code-path, for sandbox and endpoint
delete, they try to load the plugin and it causes daemon startup
timeouts since the external plugin containers cant be loaded at that
time. Since the cleanup is actually performed for the libnetwork core
states, we can force delete sandbox and endpoint even if the driver is
not loaded.

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.
