As it was decided that the name "tags" would be better for the clarity
of the feature, all files and code named "cluster" or "worker cluster"
have been removed and replaced with "tag" and "worker tag". This is only
a name change, no other features were touched.
This addresses part of #104204.

As a note to anyone who already ran a pre-release version of Flamenco
and configured some worker clusters, with the help of an SQLite client
you can migrate the clusters to tags. First build Flamenco Manager and
start it, to create the new database schema. Then run these SQL queries
via an sqlite commandline client:
```sql
insert into worker_tags
(id, created_at, updated_at, uuid, name, description)
select id, created_at, updated_at, uuid, name, description
from worker_clusters;
insert into worker_tag_membership (worker_tag_id, worker_id)
select worker_cluster_id, worker_id from worker_cluster_membership;
```
The Flamenco add-on can now find the top-level directory of your Blender
project. It can be configured to find any of these directories:
- `.blender_project`
- `.git`
- `.subversion`
- None, which is the default and the old behaviour of just using the
directory of the current blend file as the 'project directory'.
Before submitting a job, the add-on now checks the version of the Manager.
If this is not the same version of the add-on, a warning is shown and a
"Force Submit" button appears. This makes it both explicit that something
is iffy and still allows for pushing forward.
This is important when upgrading Flamenco, because I'm sure many people
will forget to actually redownload and reinstall the add-on.
Flamenco now no longer uses the Git tags + hash for the application
version, but an explicit `VERSION` variable in the `Makefile`.
After changing the `VERSION` variable in the `Makefile`, run
`make update-version`.
Not every part of Flamenco looks at this variable, though. Most
importantly: the Blender add-on needs special handling, because that
doesn't just take a version string but a tuple of integers. Running
`make update-version` updates the add-on's `bl_info` dict with the new
version. If the version has any `-blabla` suffix (like `3.0-beta0`) it
will also set the `warning` field to explain that it's not a stable
release.
The add-on code was copy-pasted from other addons and used the GPL v2
license, whereas by accident the LICENSE text file had the GNU "Affero" GPL
license v3 (instead of regular GPL v3).
This is now all streamlined, and all code is licensed as "GPL v3 or later".
Furthermore, the code comments just show a SPDX License Identifier
instead of an entire license block.
