That is just an alias for StoreSharedPtr and all references in the repo to StorePtr have been removed, and a lint check added to prevent new ones from appearing.

However there are other repos that reference Stats::StorePtr and they need a chance to clean up their references. 2 I know of are internal to Google (CL pending) and Nighthawk -- code changed; haven't issued PR yet.

We should do a community-meeting call to remove refs to StorePtr first and then write the final PR to delete it.
