Remove mysql setup

bifrost sets up the mysql database itself, we can remove the setup from
project-config now.

Note that change I8485751eda745841c1436ecd766c9bb95446f407 has been
merged to all branches excpet mitaka since that branch is broken.

Proposal is to move forward without change in mitaka - and add it there
if critical changes need to go in.
