`ssl.wrap_socket` is deprecated since python 3.7 and since python 3.2
and 2.7.9 (released in 2014) it is recommended to use the
SSLContext.wrap_socket() instead of wrap_socket(). The top-level
function is limited and creates an insecure client socket without server
name indication or hostname matching [1].

Python 2.7 is now officially unmaintained, latest version of
python 2.7 is 2.7.18, py-amqp only support python versions who are compatible
with these changes [2].

These changes move away from `ssl.wrap_socket` by using
now `ssl.SSLContext.wrap_socket` [3].

I have a microservice=y project where I'm using py-amqp extensively. In the development environment I would guesstimate that 90% of the debug logs from these services are from `amqp.connection.Connection.heartbeat_tick`.

I still want to see all the other debug output, but selectively filter out the heartbeat debug from my own code via
`logging.getLogger('amqp.connection.Connection.heartbeat_tick').setLevel(logging.INFO)`.
