Houdini: Publishing workfiles

[antirotor]

Feature

This is adding ability to publish Houdini HIP files as workfiles the same way as is currently done in Maya. It adds Validator that checks if paths inside specific nodes doesn't contain unresolved $HIP/$JOB variables (because one this workfile is copied to published area, those links would be broken). Validator has repair action to resolve those to absolute paths.

Validator is configurable to add more environments variable that should trigger it (albeit repair action will only resolve $HIP and $JOB)
