Use promgrafonnet as a vendored library from its source

The only deviation that happened so far is to use format="percentunit"
in a Grafana gauge. This change wasn't even properly used in this repo
so far, so I opted to stick with "upstream" for now. If changes are
really needed, we can try to change upstream first.

Another change was done in parallal here and upstream, but it was
"more correct" in upstream. (Change datasource to $datasource
variable, only partially applied here.) Which is another point for
using the upstream and not copy it here.
