Add sys command for powercycle on host shutdown.

The new command will trigger a power cycle the next time the host shuts
down. This can exist in parallel with the existing mechanism to trigger
a power cycle after a specified time interval.

The implementation of host state detection and power cycling is platfrom
specific; the new command will just add a temporary file that marks the
system ready to powercycle on the next shutdown. Usually, a systemd unit
would be enabled by the presence of this file to handle the power
cycling process.

Using global variables that have construction order dependencies on each

where the defaultConfigPath is not constructed from the string in

entirely.
