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.

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.

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

Moves two config options, namely EnableIPTables and EnableUserlandProxy
from networks to the driver.

1. replaced --net option for service UI with SERVICE.[NETWORK] format
2. Making using of the default network/driver backend support
3. NetworkName and NetworkType from the UI/API can be empty string
and it will be replaced with DefaultNetwork and DefaultDriver
As per the design goals, we wanted to keep libnetwork core free of
handling defaults. Rather, the clients (docker & dnet) must handle the
defaultness of these entities.
Also, since there is no API to get these Default values from the
backend, UI will not handle the default values either. Hence, this falls
under the responsibility of the API layer to handle this specific case.

The configuration format for docker runtime is based on daemon flags and
hence adjusting the libnetwork configuration to accomodate it by moving
the TOML based configuration to the dnet tool.

In one of the previous commit, we went to the extreme of supporting just
the /{version}/networks. Though that satisfied the requirements for UI
integration, it is not fully consistent with Docker APIs.
Docker API supports both /{version}/resource and /resource and hence we
must add the same support for networks resource.
Also fixed a silly bug in api.go

Though libnetwork api is supposed to handle the sub router, it is given

This is need to decouple types from netutils which has linux
dependencies. This way the client code which needs network types
can just pull in types package which makes client code platform

Refactored the driver api so that is aligns well with the design
of endpoint lifecycle becoming decoupled from the container lifecycle.
Introduced go interfaces to obtain address information during CreateEndpoint.
Go interfaces are also used to get data from driver during join.
This sort of deisgn hides the libnetwork specific type details from drivers.
Another adjustment is to provide a list of interfaces during CreateEndpoint. The
goal of this is many-fold:
* To indicate to the driver that IP address has been assigned by some other
entity (like a user wanting to use their own static IP for an endpoint/container)
and asking the driver to honor this. Driver may reject this configuration
and return an error but it may not try to allocate an IP address and override
the passed one.
* To indicate to the driver that IP address has already been allocated once
for this endpoint by an instance of the same driver in some docker host
in the cluster and this is merely a notification about that endpoint and the
allocated resources.
* In case the list of interfaces is empty the driver is required to allocate and
assign IP addresses for this endpoint.
