Better handle refreshing identities
When mordred refreshes identities for a project, it refreshes all identities for every project. This becomes very time consuming after just a few large projects have been indexed, and severely slows down the scanning of even single-contributor projects (on the order of 10x, a few minutes -> a half hour).
One possible solution is to disable automatic identity refreshes, but this would have future consequences for account integrations.
Another possible solution is an upstream fix of some sort.
Open discussion welcomed.
