Support Neutron L2GatewayConnection resource

The Neutron extension for layer2 gateway (networking-l2gw) provides a API to
manage L2GW components. The proposed change is to implement two new Heat
resources to allow management of the L2GW and L2GW-connection resources.
This change implements the 2nd of two resources,
OS::Neutron::L2GatewayConnection

features:
- New resource ``OS::Neutron::L2GatewayConnection`` to allow management of
Neutron Layer2 Gateway Connection. This resource provides capability to
connect a Neutron network to a Layer2 Gateway.
The resource depends on the Neutron ``l2-gateway`` extension.
