Upgrade to support v17

[almoehi]

Changes:

The most "breaking" change is addition of the ```label feature. I gues this will break the JSON parsers in some cases.

The build supports LABEL command. Use this to add metadata to an image. For example you could add data describing the content of an image.

LABEL "com.example.vendor"="ACME Incorporated"
