Report metrics to Dockstore

[unito-bot]

We should be able to use Dockstore’s metrics reporting to report workflow runs to Dockstore, if users want to.

How will we know if a workflow is in Dockstore if it’s not run just by a copy-pasted Dockstore URI?

How will we let users turn this on and off, exactly?
