Adding an explicit token name makes it easier for people to find it again.

I feel like this is not complete, but I jotted down what I knew.

The alert was added during phase A of the migration to prometheus but I
had not written anything about how to handle those situations.

This goes with the new alert for this condition.

surely not exhaustive, but what I could think of off the top of my head.

This was succesfully performed to restore weather-01 on a test-01
server, not even hooked in Puppet.

this updates the puppet control repo proposal to account for the fact
that the repository would track an environment as opposed to /etc/puppet
altogether

it also adds to the proposal renaming hiera -> data, site-modules -> site and
adding "legacy" to the environment modulepath which would contain all
modules which still need to be either published as a public module or
transformed into a profile

note that while I've tried to retain consistency with "step 0" of
publishing our puppet code, I don't think we should maintain this goal,
let alone keep it as the very first step before everything else

Closes: team#41937

We should have better docs about how we monitor Puppet server and agents
with Prometheus...
