Reshaping repo
The repo is designed for use with an existing builds.sr.ht service.
Besides lacking that, I am more interested in a containerized workflow
powered by a Makefile. Package source code will live in `pkgsrc/`,
packages will be built into `pkg/`, and packaging keys will be
generated into `keys/`.
Alos trimmed the packages down to what I will build.
*.sr.ht: Enable prometheus multiprocessing mode
meta.sr.ht: overhaul init files
meta.sr.ht: use app, not app_dispatch, w/gunicorn
The latter has been removed now that instrumentation is built into
core.sr.ht.
Fix supervisor in meta.sr.ht init scripts
meta.sr.ht: normalize init scripts
Make local redis service optional
Add extra gunicorn args to *.init
Fix more indentation issues
Update meta.sr.ht for prometheus support
Rename meta.sr.ht init script
