The synchronous version of REST client supports basic retries through urllib3 library using the retries configuration parameter. The asyncio version should support the same behaviour such that the retries parameter can be honoured in this version.

I attempted a change to the template files that would appear to handle the case using the aiohttp-retry library. There were no tests for retry in the synchronous version so I have not added any to this change. Please feel free to improve upon this, the feature would be useful.
