Closes-Bug: #1573654
(cherry picked from commit be8c615bb0)
Cap tempest to 12.2.0 as the call_until_true has been deprecated after
13.0.0.
test.call_until_true has been deprecated since Newton on Tempest side,
and now Tempest provides test_utils.call_until_true as the stable
library method. So this patch switches to use the stable method before
removing old test.call_until_true on Tempest side.
