Default workspace behaviors

[ddementieva]

Following the discussion we had during the R&D call of Tuesday 23th February, we need to change the default behaviors of workspace states.

When, a new workspace is created: it always start from a base image.

When a user is working in a workspace, we need to:

• auto-snapshot the state of the workspace where we are shutting it down
• auto-restore the latest workspace's snapshot when the user come back to his work.

This way, the default behavior will be that the user will get his workspace in the exactly same state as it was when he leaves it.

This behavior, must be a default behavior handled by the server for all clients - so clients must not manage that logic.

After some brief internal discussion. We think that you proposal may have unwanted problem with performance.
On the first stage we propose to add workspace configuration parameters one for auto-snapshot and one for auto-restore
Is that ok for you?

Okay.

Then it means that this behaviour will be configurable per workspace, right?

query parameter "?start=true"
auto-snapshot the state of the workspace where we are shutting it down
auto-restore the latest workspace's snapshot when the user come back to his work.
One workspace attribute. Default false.

I would make 2 self explained parameters, one for start one for backup, like
"start-after-create" - whether the workspace automatically started after creation
"auto-use-backup" - whether the workspace will create snapshot automatically after stop and use it after start
