Async_test

Toy example of asynchronous requests with retries. Program will count tags on github repos in 2 ways: using requests library and aiohttp.

Program counts tags on github repos. There are 5 params:

1. --query - Query for repos search.
2. --pages-count - Pages count where tags will be counted. Default = 1.
3. --top - How many top tags to show. Default = 1.
4. --timeout - Timeout for cases when status code != 200. Default = 1.
5. --retries-count - Retries count for cases when status code != 200. Default = 1.

Sometimes for big values of --pages-count sync and async approaches can show different results. The reason of that is GutHub.com defence versus abuse.
