Refactor mysql element to do less in first-boot.d

Browse Source 
We didn't need to do most of this anyway, we just needed to configure
mysql before we installed the packages in the image. Some of the other
things were half-baked ideas which will come in later changes to add
os-refresh-config and os-config-applier support to the element.
