    Add a regression test for bug 1939545

    Assert the behaviour of the libvirt driver during pre_live_migration
    with instances that have block based volumes attached.

    Bug #1939545 covering the case where the returned path from os-brick
    isn't being saved into the connection_info of the associated bdm in
    Nova.

    The cinder fixture is extended as part of this change to offer
    connection_info listing the iscsi volume type in order to correctly
    assert the behaviour of the associated libvirt volume driver.
