Description

Improve the implementation in platform-api's newly introduced deploymenttransform package to transform artifact to gateway compatible version.

• Instead of policies.go add logic against kind instead
• Introduce packaging for each gateway version
• For each version specific kind transformation, take as input the to and from version and write transformations ensuring scalability
