tags: write a separate tags cache file for unfiltered repos Since we changed the format of the tags cache, we should bump the filename. Before this patch, "tags" was being used for unfiltered repositories. Change the naming scheme to be consistent and ensure that a new cache file is used. While I was here, I updated the docs to describe the existence of multiple caches. I also added explicit test coverage for the creation of the unfiltered tags cache.
