Subject: [PATCH] v-m: Update jobs for new Loki server

*loki1.pyrocufflink.blue* is a regular Fedora machine, a member of the
AD domain, and managed by Ansible.  Thus, it does not need to be
explicitly listed as a scrape target.

For scraping metrics from Loki itself, I've changed the job to use
DNS-SD because it seems like `vmagent` does _not_ re-resolve host names
from static configuration.
