Instantiating BlockingConnectionPool.from_url with timeout in query args fails

[r0ro]

Version: 5.0.1
Platform: All
Description: Missing cast in URL_QUERY_ARGUMENT_PARSERS for "timeout" parameter causes a runtime TypeError

When instantiating a BlockingConnectionPool from url with timeout query parameter, timeout is not cast to float, resulting in timeout to be set to string in BlockingConnectionPool.init.

Later on when attempting to use the BlockingConnectionPool, comparison of timeout (as a string) to an int causes a TypeError '<' not supported between instances of 'str' and 'int'

TestCase:

>>> from redis.connection import BlockingConnectionPool
>>> pool = BlockingConnectionPool.from_url("redis://127.0.0.1:6379/1?timeout=42")
>>> pool.timeout
'42'
>>> pool.get_connection("PING")
