Code Issues Proposed changes

Add MTU information in DB and API 

MTU value can be different for each neutron network.
E.g. for high-performance use-cases it's very important to also
support MTU's with jumbo frames.

This patch exposes this information to the drivers. Each driver
should setup its resources accordingly.

The tempest test actually just covers the api change. Better coverage will
be added when the container driver lands.
