[resubmission] DCL-Metrics - fundamental community metrics #2

After gathering feedback from many of you in the past weeks since our previous attempt, we have decided to try again for a continuation grant to not only keep DCL-Metrics alive but expand the metrics we offer. We are looking forward to getting back to work!

The main things we want to implement are quality of life features to make the grant process easier to track and understand for grantees, the GSS and the community at large. Please see full description below.
