RFE: Add version information

[gnunn1]

I have the opensource policygenerator on my system but running into an incompatibility with v2.7 of the ACM version. There doesn't seem to be any way to get it to output it's version?

Thanks for the RFE, @gnunn1! Indeed we don't currently have version information embedded, so this would be a great addition!

@gnunn1 I've implemented a --version flag for the binary but the way it's pulled into the subscription container it won't work. I'll need to follow it up with an additional PR.
