Description of problem:
When migrating

Version-Release number of selected component (if applicable): MTC 1.5.2

How reproducible:
Always when migrating HPAs from Openshift 3.x to 4.x

Steps to Reproduce:
1. Migrate a project based on a Openshift 3.x cluster containing a deploymentconfig and a horizontalpodautoscaler that scales this deployment config. Check that on the destination 4.x cluster, the apiversion/kind of the spec.scaleTargetRef of the migrated HPA is not using the updated GVK of DeploymentConfig on Openshift 4.x

Actual results:

• hpa.spec.scaleTargetRef.apiVersion is "v1"

Expected results:

• hpa.spec.scaleTargetRef.apiVersion should be "apps.openshift.io/v1"

This bugfix needs to be included in OADP 1.0.3 for the next MTC release.
