[Devtools] CDK 2.4 and Minishift CDK uses lots of CPU

[Burr Sutter]

CDK 2.1 could also handle the laptop sleep cycle pretty well (at least 4+
sleep/wake cycles) but I do not believe CDK 2.3 could as one sleep/wake
cycle could cause it to "eat all the CPU".   In my case, I always use the
CDK 2.x with Virtual Box
and the Minishift CDK with Xyhve
