AIOHTTPTransport ssl=False by default #529

• TLS should be enabled by default. AIOHTTPTransport uses ssl=False by default
• I was expecting library to fail when using self signed certificate on the server.

To Reproduce

• start a server with a self signed certificate
• try connect
• it will succeed instead of failing

Expected behavior
Expect connection to fail when using not trusted certificates
