fix crd schema

[tchughesiv]

fixes this error seen in ocp4.3.5 when crd is installed -

[spec.version[v2].schema.openAPIV3Schema.type: Required value: must not be empty at the root, spec.version[v1].schema.openAPIV3Schema.type: Required value: must not be empty at the root]

adds printer columns -

$ oc get kieapp
NAME          VERSION   ENVIRONMENT   STATUS     AGE
rhpam-trial   7.8.0     rhpam-trial   Deployed   5m5s
test          7.8.0     rhpam-trial   Deployed   3m55s

[WIP] allow oc explain to work as expected as well??
