API for teams

[juliushaertl]

Part of #42433

In order to implement the different integration parts across apps we need a public API that allows

• List all providers that can share to a team (circle)
• List all entries of each providers that are shared with a given team (circle)

Example:

• Have a deck provider that list all deck boards shared with a circle
• Have a collectives provider that returns the collective of a given circle (there is only one as of right now)

To be clarified if in scope

• Create a new share with a team through a generic API
