hockeypuck snap doesn't logrotate correctly

When I explored doing this properly via snaps I ran into a bunch of problems and ended up deploying a workaround: https://wiki.canonical.com/InformationInfrastructure/IS/HockeypuckKeyserver#Logging

This override seems to have been clobbered around February 25 by another SRE's override file. I guess they didn't check to see if one existed already. I'll add it back.

My notes from Back Then: https://pastebin.canonical.com/p/4Xh4DVrG79/

Oh, also, to be clear, that logrotate file is something we installed quasi-manually with a Mojo script (my bad for not adding a comment) not something the snap supplied.

Certainly proper reload supports would be useful, though.

To sum up the notes from above if you can't read them (whether because the link is private or because it's such an incoherent ramble) I eventually discovered that the snap-confined reload command could not send SIGUSR1 to hockeypuck (possibly even would not work unconfined with Ubuntu's default security settings) and so reload probably has to be implemented by having hockeypuck receive the command via an admin socket in /var/snap/hockeypuck/common or such.
