Slawek Kaplonski e3be3f913c [OVS] Add mac-table-size to be set on each ovs bridge 
By default number of MAC addresses which ovs stores in memory
is quite low - 2048.

Any eviction of a MAC learning table entry triggers revalidation.
Such revalidation is very costly so it cause high CPU usage by
ovs-vswitchd process.

To workaround this problem, higher value of mac-table-size
option can be set for bridge. Then this revalidation will happen
less often and CPU usage will be lower.
This patch adds config option for neutron-openvswitch-agent to allow
users tune this setting in bridges managed by agent.
By default this value is set to 50000 which should be enough for most
systems.
