mod_s2s: Add event where resolver for s2sout can be tweaked

Could be used to implement custom connection methods (c.f. mod_onions)
without needing to duplicate the rest of route_to_new_session().

Adds a feature to enable detection since it can be difficult to detect
support for an event otherwise.
