Comment 4 for bug 1491782

I suspect mysql isn't booted and the VM is setup with one processor, so a priority inversion is happening not permitting mysql to schedule enough to get to an operational state before ansible tries to create the haproxy database user.

Recommend try adding a wait for for port 3306 at the end of mysql (the next step after mysql orchestration is the creation of this database user).
