+    Fixed bug #1890060. tempest subunit_describe_calls --verbose not working with Cliff CLI.
+    The subunit_describe_calls --verbose argument was a boolean and worked in the non Cliff CLI
+    which is now deprecated, but does not work with cliff since --verbase is a standard cliff
+    argument which is an int.  Since the tool is in lib directory we cannot change the interface,
+    so we add a new argument -a --all-stdout that will allow cliff CLI to support the
+    feature in subunnit_describe_calls to print request and response headers and bodies
+    to stdout.

+  - Add a new config option can_migrate_between_any_hosts in the
+    compute-feature-enabled section, which can be set to False for environment
+    with non homogeneous compute nodes, so that it can select a destination
+    host for migrating automatically, otherwise the testcase may fail
+    unexpectedly. e.g., if source host is with CPU "E5-2699 v4" and the
+    selected target host is with CPU "E5-2670 v3", the live-migration will
+    fail because of the downgrade issue.
