Fixes for linux bridge and Q_USE_PROVIDER_NET
===Set bridge_mappings for linux bridge=== The external network physnet needs a bridge_mapping to the public bridge when the L2 agent is responsible for wiring. ===Add PUBLIC_PHYSICAL_NETWORK to flat_networks=== This network must be present in the ML2 flat_networks config if flat_networks is specified. ===Set ext_gw_interface to PUBLIC_BRIDGE in provider net case=== ext_gw_interface must be a bridge in a bridge_mapping when Q_USE_PROVIDERNET_FOR_PUBLIC is used. Closes-Bug: #1605423 Change-Id: I95d63f8dfd21499c599d425678bf5327b599efcc
