In a bunch of cli tests we check how tenant isolation works, for
this we authorize as an admin user and as a alt user.
Prevously we used tempest config and took credentials from it,
in this config user alt_username was equal to 'alt_demo', that's why
there weren't any problems during all tests execution on every commit
to mistral repo, cause api tests run under 'demo' user, cli tests under -
admin and alt_demo. Now after removing usage of tempest config we use
'demo' user as an alt_user, that's why we have conflicts, when after
api tests action executions are left and we get them during cli tests.
