have to redeploy baremetal instances when changing network interfaces

[Robert Collins]

when a node has an instance deployed to it (or one trying to deploy) and the network card is wrong, the solution (after physically swapping out the NIC) is to run 'nova baremetal-interface-add <id> <nic MAC>'

but - neutron doesn't get told about the update, so the port registration is wrong, and DHCP will fail. As a result you need to nova delete + nova boot, which is more disruptive than necessary.

    Add TaskManager lock on change port data

    Updating port data may require driver actions on the related node
    (if address changed for example). New method 'update_port' added
    to conductor manager and rpcapi.
