Integration with MC&I infrastructure

Once we are able to produce nice pages documenting requests, we can create them automatically from MC&I infrastructure to help with the validation.

This could take the form of a CI job in B2G's version of https://gitlab.cern.ch/cms-exo-mci/EXO-MCsampleRequests [docs], producing the HTML for all open merge requests and making them available via GitLab pages.
