1. Fix monasca-grafana by pinning more Ruby gems
childprocess 3.0.0 and ffi 1.13.0 depend on Ruby 2.3.
2. Bump bifrost to 6.0.4
Bifrost had a fix to stop using the master branch of DIB which dropped
support for Python 2.
3. Drop docker-client from OracleLinux sensu-client image
The package fails to install due to a missing dependency on
subscription-manager.
Closes-Bug: #1882070
(cherry picked from commit 3784d32d9c)
3. CI: Install python deps, mark oraclelinux rsyslog as skipped
setuptools is missing from infra image - so it needs to be installed.
Copy cat of a kolla-ansible change: https://review.opendev.org/#/c/735808/
Disables rsyslog build on oraclelinux (both source and binary) and
tripleoclient (binary).
4. Stops installing ansible (this is the build part, kolla-ansible has
its own repo and jobs).
5. Use stable/rocky branch for bifrost
