If/when this is merged, a follow up PR to CCR will be required to bump the 7za.exe that is stored there to be the same version, so that everything is consistent.

I've taken this for a spin with the Intune integration, it's all working as expected. I'm just running a test kitchen run against it, will know before Monday if there's any issues with those tests.

Well that didn't go quite as planned...

Those 15 failed are expected due to the build identifying as `0.12.1-alpha` and those tests only skipping if the version is 1.0.0 or greater. (those tests being that we're reporting the existence of the version command which is gone)

@corbob thanks for taking this for a spin!
