* feat: cli: consolidate schedule-related commands This commit makes the following changes: - renames autostart -> schedule starat - renames ttl -> schedule stop - renames bump -> schedule override - adds schedule show command - moves some cli-related stuff to util.go
* Changes all public-facing codersdk types to use a plain int64 (milliseconds) instead of time.Duration. * Makes autostart_schedule a *string as it may not be present. * Adds a utils/ptr package with some useful methods.
