Allow passing any valid backend connection kwargs via BaseCache

* Pass `**kwargs` to backend storage classes, split out any that are valid for the backend-specific connection function/class, and pass them to the connection
* Add intersphinx links to docs for dependencies
* Update and format some more backend class docstrings
* Remove 'Unrecognized keyword arguments' warning from `BaseStorage`
* Turn `warnings.warn` about using secret keys into a `logging.warning` (due to complaints about too many messages)
