github-graphql.js: Fix several issues

1. Fix bug: GraphqlClient class was instantiated
   with wrong arguments.

2. Remove redundant code: _updateRateLimit function
   is defined twice.

3. Remove script/queries/*.js files and refactor
   script/index.js.

4. Retry threshold is changed to be based on repo.
