Maintainer Recommendation 2.0

[asamalik]

Content Resolver can recommend maintainers of shared dependencies in views.

However, it only takes the workload definitions and the dependency information into account. It doesn't allow maintainers to arbitrarily volunteer to own something (like a Python maintainer offering to own some Python-related packages, without necessarily pulling them in themselves).

I want to add a functionality to allow maintainers to explicitly maintain a package. This needs to then influence the dependency recommendations, too.
