CMP-2130: Implement support for profile versioning

This commit adds support for an optional version attribute for Profile
custom resources. This attribute is parsed out of the datastream and set
on the Profile by the compliance operator. It's not intended for end
users to supply their own version.

Future patches may expand on this concept to support multiple versions
of a single profile.
