    [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).

    Fixing:
    - bug#1885825
    Fix user creation with GRANT in MySQL 8.0(Ubuntu Focal)
    Ubuntu Focal (20.04) has mysql 8.0 and with mysql 8.0 there
    is no implicit user creation with GRANT. We need to
    create the user first before using GRANT command.

    - bug#1886298
    Bump the lower constraints for required deps which added python3.8 support
    in their later version.
