It would be helpful to see HEAD's SHA included in --version output for crio(ctl).

This became apparent when looking @ latest drop of kubernetes-the-hardway and wanting to know what branch/release matches 'v1.0.0-beta.0.' Looking at the sources, there is a matching TAG for this in release-1.6 branch (and master), though the version updated in the source tree (app.Version) was updated considerably later in the source tree.

Having a SHA would make these all very clear.

Let me know what you all think. If you agree I can put this on my to-do-list.
