Recreate iaqualink httpx client upon service exception

[flz]

Breaking change

Proposed change

Every hour, the iaqualink backend closes the http connection. Somehow, the httpx client doesn't restart the http connection so the best way we have to deal with the issue is to re-create the httpx client instance. That's being done here by force-closing the client via a library call.

Also, catch httpx Exceptions in await_and_reraise() which was forgotten in the previous fix.
