Remove call_until_true from test module

The call_until_true of test module is marked as deprecated and
we have a plan to remove it in Ocata cycle.
This patch removes it after switching to use test_utils' one on
all OpenStack projects.

+upgrade:
+  - The *call_until_true* of *test* module is removed because it was marked
+    as deprecated and Tempest provides it from *test_utils* as a stable
+    interface instead. Please switch to use *test_utils.call_until_true* if
+    necessary.
