Add query parameter parsing to ParseURL()

Browse Source 
Before this change, ParseURL would only accept a very restricted
set of URLs (it returned an error, if it encountered any parameter).

This commit introduces the ability to process URLs like

	redis://localhost/1?dial_timeout=10s

and similar.

Go programs which were providing a configuration tunable (e.g.
CLI flag, config entry or environment variable) to configure
the Redis connection now don't need to perform this task
themselves.
