Message 272203 - Python tracker

Hm, I'm working on adding connect_accepted_socket to the uvloop.  There is one difference between connect_accepted_socket and create_server/create_unix_server:  the latter APIs forbid to pass boolean `ssl` argument, they require `ssl` to be an instance of `SSLContext`.

Should we have the same requirement for the 'ssl' argument of newly added 'connect_accepted_socket'?
