This reads tags input from swh-apps repository and adapts accordingly the targetted
values.yaml.

At the moment 2:
- generate-frozen-requirements
- list (with/without parameters)

This will ease reusing the same docker image for multiple calls to subcommands.

Ref. swh/infra/sysadm-environment#4724

The script opens whatever apps has the module name [1] in its current frozen
requirements. If the constraint of module name and version does not match, it outputs
said application as being impacted.

Example calls:
```
./scripts/list-apps-to-rebuild swh-loader-core 5.2.0
./scripts/list-apps-to-rebuild swh-loader-core v5.2.0
```

This allows to build the container that will call the generate-frozen-requirements
script.

That will be usable from ci or other sysadm.

Use:
```
cd swh-apps/scripts
docker build -t build-deps .
cd ../../swh-apps
docker run -v $PWD:/src --user 1000 build-deps $APP
```

It used to be necessary for subvertpy packaging.

This creates a new utility image holding the rsvndump pushed in the gitlab registry.

And then adapts the svn loader image to expose that new dependency tool [1]. That will
allow development to use rsvndump instead of svnrdump.

[1]
```
$ docker build -t swh-loader-svn .
$ docker run -ti --rm --user root --entrypoint rsvndump swh-loader-svn --version
rsvndump 0.6.1

This avoids keeping around a useless shell process, and allows killing
the "init" process to always DTRT

The fossology license indexer requires the fossology-nomossa package.

As a pre-requisite, it was ported from the buster package:
```
root@pergamon:.../repository# reprepro copy bullseye-swh buster-swh fossology-nomossa
Exporting indices...
root@pergamon:.../repository# reprepro ls fossology-nomossa | grep bull
fossology-nomossa | 3.1-1~bpo10~swh+1 | bullseye-swh | amd64
