    * Update monasca-persister from branch 'master'
      - [goal] Migrate testing to ubuntu focal
    
        As per victoria cycle testing runtime and community goal[1]
        we need to migrate upstream CI/CD to Ubuntu Focal(20.04).
    
        Bump the pyflakes to 2.1.1 as min version to run pep8 jobs
        on py3.8 which is default python vesion in ubuntu focal.
    
        Bump cassandra-driver to 3.21.0 in lower-constraints.txt
        since it is the min version with py3.8 support [2]
    
        Bump kazoo to 2.8.0 in lower-constraints.txt
