Currently we rely on watch to catchup after the init. But there could be
a small time window on which, we might end up in a race condition on
network creates. By reading and populating networks during init, we
avoid any such conditions, especially for default network handling.

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.
