Group/Project filtering in the Groups/Projects pages

Hi,

I'm using the Debian gitlab instance at https://salsa.debian.org. That setup has all Debian Developers in the 'Debian' group, and a lot of projects under that group.

Some groups also have “invited” the Debian group using the “share with group” feature. That mean that when I'm watching the group page at https://salsa.debian.org/dashboard/groups there are a lot of groups, in which I'm not really interested in.

The same is also true in the Projects page (https://salsa.debian.org/dashboard/projects) where I have all projects under the Debian group, but also apparently all projects from the groups which have shared their project with the Debian group.

For project I can try to star only the projects which I'm interested in, but it's a bit cumbersome, and it's not possible for groups.

Having a way to somehow filter these "external" projects and groups would be nice and really help lowering the noise and clutter in those pages.

In any case, I think the origin of these projects and groups should be displayed.

Thanks for all the work, by the way, using the Debian gitlab instance is really nice other than these few issues here and ther.
