    Use ubi9-init image as base

    CentOS-8 no longer exists and existing jobs are running
    on centos-stream-8. There will be no openstack master
    rpm packages for centos-stream-8.

    In order to use ubi9-init image in molecule jobs,
    we need to include following workarounds:
    - redhat-release package(RH specific package) is installed in ubi-init
      which does not work with centos-stream package.
      On removing redhat-release, dnf ansible breaks as they did not find
      --releasever during package installation.
      - By adding releasever in the package module fixes the issue.
    - In Molecule job, we can use any hostname either of centos or ubi both
      will work.
    - It changes the nodeset and image to ubi9.
    - Install pip < 20.3.0 to avoid https://pip.pypa.io/en/stable/topics/dependency-resolution/#backtracking
      and upstream requirements file to avoid cyclic dependency
      issue.
    - Set enable_fips: true in collectd jobs as in molecule it is not
      needed otherwise job will enter into retry_limit.

    We cannot use centos:stream9 image as, init support is removed
    from there.
