requirements.yml refers to an obsole role

cldr-runner/base/requirements.yml refers to an obsolete role

roles:

• name: geerlingguy.postgresql
  version: 2.2.0
• src: https://github.com/dbeech/ansible-role-mysql
  version: master

The role dbeech/ansible-role-mysql does not work with mySQL 8....only with and older 5.7 era mysql

I would suggest

• src: https://github.com/clevesque/ansible-role-mysql
  version: master

Agreed. I would actually like to remove this dependency completely. I think using this role is overkill for our needs.
