Currently only data fields is supported in configmap display. binaryData (even if it exist) is not shown.
kubectl -n percona-xtradb describe configmaps test1

Name:         test1
Namespace:    percona-xtradb
Labels:       <none>
Annotations:  <none>

Data
====

BinaryData
====
readiness-check.sh: 17 bytes

Events:  <none>

Why is this needed?

If would be nice if all standard types of standard kubernetes objects is shown in UI.
