[RFE] Allow names in {provisioning,cleaning}_network option

[Dmitry Tantsur]

Names are useful for humans. Let's use them for provisioning and cleaning networks.

A suggestion:
1. Rename {provisioning,cleaning}_network_uuid to {provisioning,cleaning}_network (with deprecation)
2. Accept network names in these fields
3. Only validate these network names during the network interface validate() call, but not on start up. This allows the name to be set and ironic to be brought up before the network is created, which can be useful for installers.

A suggestion to discuss: have some name as a default.

    Support names for {cleaning,provisioning}_network

    Names are easier to use for humans, so let's allow them.
    The actual name -> UUID convertion happens during validation and its
    result is cached for each interface instance.

    This change will allow recreating a network without changing Ironic
    configuration or setting a network name in advance (e.g. by an installer).

    Note that when names are used, an administrator is responsible for ensuring
    that no other networks have the same name (names are not unique in Neutron).
