Extend create_tcp_connection utility

[Creatone]

It would be a great thing to set context options and ciphers to provide better security.

Hi,

Thanks for your PR. I agree this would be a good feature. However, I noticed you only changed one method, so, for instance, the client interface will not have a way to set those parameters. Am I missing something here?

[Creatone]

Client can set this parameters in his handler.
For example:

class MySequentialThreadingHandler(SequentialThreadingHandler):
    def create_connection(self, *args, **kwargs):
        return create_tcp_connection(socket, options=MY_OPTIONS, ciphers=MY_CIPHERS,
                                     *args, **kwargs)
