In general, I think your bpfapplication CRD looks okay. As I said above, I'm going to have to think about how/whether we could use the existing code some more though.

I added a few random thoughts in comments here.

Rebased on pr #21.

I fixed some lint errors.

we may just want to remove the uprobe entry to avoid having to deploy a target

If we change the attach point to the one being used in the uprobe sample, it won't require the target. I was going to make this change at some point.
