Hello all,

I am proposing Ben and me to maintain the Exporter Toolkit repository.

Here is the pull request:

https://github.com/prometheus/exporter-toolkit/pull/40

If there are no objections, the pull request will me merged in the
coming days.

If there are objections, you can redirect them to the prometheus team,

this list for technical matters.
