realm.json should have kind `ConfigMap`

My kubernetes is case sensitive:

$ kubectl create -f realm.yml -v 5
I0318 15:44:57.377267   25048 decoder.go:224] decoding stream as YAML
I0318 15:44:57.441178   25048 discovery.go:213] Invalidating discovery information
F0318 15:44:58.127189   25048 helpers.go:119] error: unable to recognize "realm.yml": no matches for kind "configmap" in version "v1"

But when I changed configmap to ConfigMap:

$ kubectl create -f realm.yml -v 5
I0318 15:49:44.772500   25393 decoder.go:224] decoding stream as YAML
configmap/keycloak-realm created
