Before switching to the DevWorkspace engine, it was possible to specify workspaces timeout through Che server properties CHE_LIMITS_WORKSPACE_IDLE_TIMEOUT and CHE_LIMITS_WORKSPACE_RUN_TIMEOUT.

Currently Che-Theia based workspaces are idled after 15 minutes of inactivity. This is specified in the editor definition and it's not configurable by the user or by an admin (if not by patching the editor definition in the plugin registry or by publishing and using an alternative editor definition).

Note that VS Code and JetBrains IDE based workspaces are never idled and that we want to use a universal idling mechanism (there is a separate issue for that).
