REQUIREMENTS:
- kubectl (of course)
- krew "neat" plugin to remove some extra cruft
- yq to decode secrets to stringData

The resource types are:
- things to not keep
  - pod : transient, no need to keep
  - replicationcontroller : deprecated- should be replicaset now, also transient, created by dc
  - job : transient (from job), no need to keep
  - build : os-specific, transient, generated from buildconfig
- service
- cronjob
- deploymentconfig
- deployment
- statefulset
- buildconfig : os-specific
- imagestream : os-specific
- route
- configmap
- secret : may need special handling
- persistentvolumeclaim
- ingress
