Remove the prepare script, and run the two stages manually. Better
handle Black reformatting by doing a check (for the errcode) then
reformat and abort commit to review.
Make sure all of these move to the root of the repository first, then
return to where they were afterwards, using pushd/popd. This allows them
to be executed from anywhere in the repo.
1. Only build on GitLab when there's a tag.
2. Add the packages on GitLab to component "pvc" in the repo.
3. Add build-unstable-deb.sh script to build git-versioned packages.
4. Revamp build-and-deploy to use build-unstable-deb.sh and cut down on
output.
Rename "pvcd" to "pvcnoded", and "pvc-api" to "pvcapid" so names for the
daemons are fully consistent. Update the names of the configuration
files as well to match this new formatting.
