Ihar Hrachyshka 38531ca59c Revert "ML2: Configure path_mtu to default to 1500 bytes" ... This reverts commit 7a4633a9ca. Revert to using 0 as the default value for path_mtu. In most situations, underlying MTU does not differ for tunnel backed and vlan/flat tenant networks, in which case the only configuration expected from operators is setting global_physnet_mtu to the appropriate MTU value as reflecting all data paths that tenant traffic may take between nodes. But with the non-zero value set for path_mtu, if an operator would like to raise the global underlying MTU used by neutron to support Jumbo frames, both global_physnet_mtu and path_mtu need a bump, which is not ideal. So switch back to using a zero value for path_mtu, effectively making it not participating in MTU calculation, unless explicitly overridden. Left the original release note intact since it reflects the state for Mitaka. Added a release note for the change.
