    Ensure mgmt network hostname and fqdn in known_hosts

    The cloud-compute relation uses the private-address setting to
    reflect the hostname/address to be used for vm migrations. This
    can be the default management network or an alternate one. When
    this charm populates ssh known_hosts entries for compute hosts
    it needs to ensure hostname, address and fqdn for the mgmt network
    is included so that Nova resize operations can work if they use
    the hostname from the db (which will always be from the mgmt
    network).
