Ability to fetch branches containing a specific commit from the Rest API

Currently, it is possible to check all the branches that contain a commit through the UI by opening that specific commit.

It is also possible to get this information locally using:

$ git branch --contains <commit-sha>

However, for some cases, it would also be beneficial to be able to fetch this information directly from the Rest API. This could be achieve either adding a new endpoint or by adding this information to the commits endpoint payload response.
