[OE-core] [PATCH 7/8] scripts/contrib/dialog-power-control: add a trivial power prompt script

[Paul Eggleton]

If you want to do automated hardware testing but don't have a
controllable power strip this script can be useful so that you know when
you need to cycle the power.

+# Development manual "Performing Automated Runtime Testing" section)
+# and setting the following in your local.conf:
+#
+# TEST_POWERCONTROL_CMD = "${COREBASE}/scripts/contrib/dialog-power-control"
