Long story short

The ssl_context given as parameter to the Docker class is never used so you need to give a aiohttp Connector object instead of ssl_context.

Expected behaviour:

Don't have the way to give a ssl_context in Docker constructor (and be forced to use the connector parameter to pass SSL config)
OR
Use the ssl_context parameter to internaly create the connector

Actual behaviour:

ssl_context parameter is useless and we need to pass through the connector parameter to pass SSL config.

How to reproduce

import aiodocker

aiodocker.Docker(ssl_context="will work because not used")

Please explain the expected behavior so I can make a PR to fix this.
