Please include release version in binary

[JensErat]

Please include the tool's release version in the image or binary (eg. in a -version command, the help text and/or as environment variable/label). This would be very convenient for sync jobs into private registries.

I too would love to see this. Perhaps take some cues from prometheus:

$ prometheus --version
