Subject: [PATCH] Restore linuxbridge-agent compatibility

This patch partially reverts commit
15130cd5fd1688b8984d78136b97bb8de7c32b64.

This commit was desupporting ovs and linuxbridge plugins.
But the ML2 plugin can be deployed with the linuxbridge agent.

The current patch restores the linuxbridge agent configuration
file.

Closes-Bug: #1393429
