[WIP]prometheus: Convert mysqld-exporter into multi-instance
We need to monitor several independent mysql instances on the same
host. Add an additional resource that actually can be duplicated
so that more than one instance can be run at the same time.
This is still work in progress, but uploaded so it can be discussed
before more refactoring is done. Needs architecture feedback.
