Alessandro Boch 254d082cc3 Add ConnectivityScope capability for network drivers along with scope network option
- It specifies whether the network driver can
  provide containers connectivity across hosts.
- As of now, the data scope of the driver was
  being overloaded with this notion.
- The driver scope information is still valid
  and it defines whether the data allocation
  of the network resources can be done globally
  or only locally.
- With the scope network option, user can now
  force a network as swarm scoped
  regardless of the driver data scope.
- In case the network is configured as swarm scoped,
  and the network driver is multihost capable,
  a network DB instance will be launched for it.
