  --device-by-cvd-only   Terminates devices that a cvd server started
                         This excludes the devices launched by "launch_cvd"
                         or "cvd_internal_start" directly (default: false)

  --clean-runtime-dir    Cleans up the runtime directory for the devices
                         Yet to be implemented. For now, if true, only if
                         stop_cvd supports --clear_instance_dirs and the
                         device could be stopped by stop_cvd, the flag takes
                         effects. (default: true)

  --yes                  Resets without asking the user confirmation.

description:

  1. Gracefully stops all devices that the cvd client can reach.
  2. Forcefully stops all run_cvd processes and their subprocesses.
  3. Kill the cvd server itself if unresponsive.
  4. Reset the states of the involved instance lock files
     -- If cvd reset stops a device, it resets the corresponding lock file.
  5. Optionally, cleans up the runtime files of the stopped devices.)";
