[ussuri][CentOS][scenario003] Mistral Tempest failing tests with TypeError: dump_all() got an unexpected keyword argument 'sort_keys'

[yatin]

After https://review.opendev.org/#/c/636583/, mistral Needs PyYAMl >= 5.1, while we Consume PyYAML from CentOS Base Repos which is currently 3.10-11(CentOS7) and 3.12-12(CentOS8).

Tempest tests failis in CentOS7/8 promotion job with below Traceback:-

Until we handle PyYAML properly as we are going to remove CentOS7 support from ussuri after CentOS8 is ready completly, proposed pinning mistral in RDO:- https://review.rdoproject.org/r/24659

[yatin (yatinkarel)]

RDO Train+ CentOS8 releases have PyYAML-5.3-2.el8 and mistral unpinned, so closing it.
