As a user, I want to be able to enable and disable autostart / autostop for my workspaces using the CLI:

Examples:

• coder workspaces autostart enable my-workspace '30 9 * * 1-5' will enable workspace autostart for my-workspace every weekday at 0930 my local time (whatever my system time location is set to).
• coder workspaces autostart disable my-workspace will disable workspace autostart.
• coder workspaces autostop enable my-workspace '59 23 * * 1-5 Asia/Kolkata' will enable workspace autostop every day at 23:59 India time.
