Do not fail on missing logical router ports

set_gateway_mtu runs for all the gateway ports for a network
and if one of the ports get's deleted in meanwhile
whole transaction fails. Added if_exists=True so the
transaction do not fail for such deleted ports.

Also update minimal version of "ovsdbapp" required for
this.
