schema_user -> schema_autocomplete
autocomplete works

autocomplete returns total number of pages indexed for each repo/user

replaced requests with universalclient. I think it makes the code
easier to understand.

we only store the repo name, not the owner/name for autocomplete
because searching on slashes throws errors for some reason.

switched a bunch of for loops into generators to minimize memory.
meant getting rid of most of my progress indicators. Something to
try to put back in in future.

now two functions for creating bulk data - one for wiki pages,
one for autocomplete.

moved bulk data save back into index_all_repos since create_bulk_data
no longer creates all bulk data.

reset autocomplete index as well.
little fixes

job.value lists -> iterators

removed _repo_pages() early termination

github_api_client points to root of api.
