Ability to resume a session

[mikesir87]

Currently, the SDK only provides the ability to create a new session. But, if the client already has a session identifier (maybe stored in LocalStorage), it would be nice to have the ability to resume that session, preventing the need to create new containers.

In Slack, we talked about creating a pwd.resumeSession method that requires a session identifier to resume. May need to think about if there are any other config changes.

@mikesir87 @roicostas this is currently possible using the current init function in the SDK. That's how the ee-workhops work (https://github.com/play-with-docker/ee-workshop/blob/master/app/scripts/services/pwd.js#L25-L32) as you can refresh the page and you'll get the same session as before as the session_id is stored in the URL. Is there something else that you see it's missing?

The init function allows you to open a previous session based on the session_id however it does not restore the instance terminals. The resumeSession function uses the init function to restore the session and then recreates the previous terminals. This way you can continue with your previous containers, images etc
