Feature: multi-elixir process solution (elixir-repo-cloner)

[MichaelDimmitt]

Change elixir solution to a multi-process elixir solution instead of a bash multiprocess solution.

1. clean special characters out of api clone_url ... just in case
2. switch to multi process solution.
3. Only spawn 1 under max possible concurrent requests,
   after the refresh period of time only then spawn new tasks to hit the api.
4. build a notifier if the api rules ever change that lets us know we are being banned.
