def parse_connection_kwargs(server, db=None, **kwargs):
"""
Return a connection pool configured from the given URL.
For example::
redis://[:password]@localhost:6379/0
rediss://[:password]@localhost:6379/0
unix://[:password]@/path/to/socket.sock?db=0
Three URL schemes are supported:
redis:// creates a normal TCP socket connection
rediss:// creates a SSL wrapped TCP socket connection
unix:// creates a Unix Domain Socket connection
There are several ways to specify a database number. The parse function
will return the first specified option:
1. A ``db`` querystring option, e.g. redis://localhost?db=0
2. If using the redis:// scheme, the path argument of the url, e.g.
redis://localhost/0
3. The ``db`` argument to this function.
If none of these options are specified, db=0 is used.
Any additional querystring arguments and keyword arguments will be
passed along to the ConnectionPool class's initializer. In the case
of conflicting arguments, querystring arguments always win.
NOTE: taken from `redis.ConnectionPool.from_url` in redis-py
