Add project profiles table to My Profiles page

From a Slack conversation:

I realized while I was talking with some unfamiliar Cloudlab users that it is nontrivial to list all profiles in your projects. For instance, this user was trying to find the vbg-net profile in the SafeEdge project. He went to the My Profiles page, and of course it is not there, because I (dmjuser) wrote the profile. Of course he realized he could find it by starting an experiment and clicking Change Profile, but he really wanted the Show Profile page so he could consider copying the profile -- and he missed the Show Profile button in the start experiment page. So I am wondering if it might be a good idea to also show profiles in my projects on the My Profiles page, in a secondary table. We have this info already in the UI; if you clickk Membership and then the project the profile is in, you get that list.
