    Add functional recreate test for bug 1819963

    When resizing a server that was not created in an explicit
    zone, the scheduler can pick a host in another zone and
    conductor will update the instance.availability_zone value
    for the new dest host zone.

    The problem is when reverting the resize, the server goes
    back to the original source host/zone but the
    instance.availability_zone value in the database is not
    updated which can lead to incorrect results when listing
    servers and filtering by zone.

    This adds a functional recreate test for the bug.
