chore: optionally allow to use a separate collection repo

When developing new features which involves using newer collection
we need access to the collection in the image. When doing a developer
build of an image provide a build arg for the name of repo

e.g.
```
podman build --build-arg DEVEL_COLLECTION_LIBRARY=1 --build-arg DEVEL_COLLECTION_REPO=git+https://github.com/mkanoor/event-driven-ansible.git,pg_listener -t localhost/ansible-rulebook:latest .
```
