We used to have a huge hack where RBTools would do a bunch of stuff to try to find the local repository, but then the client could replace the entire repository info structure. In 3.0 we cleaned all this up to add the `update_from_remote` method, which would let the client fetch whatever data it needed. When we did this we kept the old methods around with a deprecation warning because third party tools and scripts could potentially still be calling them. This change finally removes the methods. Testing Done: Ran unit tests.
