Update bifrost SHAs

Update bifrost SHAs

There is a bug when ironic communicates with rabbitmq due to a parameter
deprecation. This patch fixes it:

https://review.openstack.org/#/c/609499/

And we can take the opportunity to update all SHAs

THere is a problem:

"Unable to retrieve file contents\nCould not find or access '/home/opnfv/releng-xci/xci/infra/bifrost/playbooks/roles/common/venv_python_path.yml'"}

That file is in:

/home/opnfv/releng-xci/.cache/repos/bifrost/playbooks/roles/common/venv_python_path.yml

As I am not sure how to fix the ansible PATH, for the time being, I just
added to where Ansible is searching for it
