    Make the cloud-compute relation net spaces aware

    When nova compute is deployed with multiple network interfaces
    configured. It may be necessary to specify which interface to use for
    the cloud-compute relation.

    Do not use unit_get('private-address') which gives unpredictable
    results. Instead, leverage network-get for network spaces aware address
    selection.

    Charm helpers sync to pull in generalized get_relation_ip() used in
    other charms which checks network-get after checking for all of the edge
    cases including IPv6 and config overrides. Use get_relation_ip() for
    address selection.

    This allows for specifying a network space in a bundle when using MAAS
    2.x. This guarantees the charm will select the correct interface and IP
    for the network space.
