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.
- Move functional jobs to Focal nodeset
Closes-Bug: #1886298
Story: #2007865
