More proxy_with_retry helper arguments (#136)

* Add `min_wait_seconds` argument to `proxy_with_retry` helper

* Add `retryable_exceptions` argument to `proxy_with_retry` helper

This allows non-aiohttp calls to use the helper to retry proxy related
requests.

* Stricter type for `retryable_exceptions`
