ProxyClientSession options can be consolidated

Created as a follow up to a review comment.

new_session->outbound_ip4       = options.outbound_ip4;
new_session->outbound_ip6       = options.outbound_ip6;
new_session->outbound_port      = options.outbound_port;

This could be logically grouped in an options member, such that the following would result:

new_session->options = options;

This is still a valid issue.
