Add support to the latest aiohttp-retry

[sshishov]

Issue Summary

Pinning aiohttp-retry to the older version potentially hold the update for other libraries which are using the same library.
In the original repo's issue inyutin/aiohttp_retry#107, it was pointed out, that MockResponse should have a properly method. I guess it is quiet easy to add in the http tests?

This is the original issue when the pin was added: #819
