[devstack] incorrect external_network ID is assigned when deploy murano with multi-regions

[Oleh Baran]

Bug description:
Currently we have such situation when after deployment devstack with multi-region support the same external_network ID is assigned to both regions, however each region should have its own external_network ID.

    Use openstack-client variables in openstack CLI calls

    In the change https://review.openstack.org/#/c/364885/ was
    introduced fix for murano multiregion setup in case of
    network determination.
    We've explored that this patch may have negative impact
    for multiregion installation (like freezes of the installer).

    In this patch important variables were changed to openstack CLI
    style and completely should fix this problem.
