> Attempting to use the RestMetricsPropertyProvider with nested metrics results in a ClassCastException.
> {code}
> Caused by: java.lang.ClassCastException: com.google.gson.internal.StringMap cannot be cast to com.google.gson.JsonElement
>  	at org.apache.ambari.server.controller.metrics.RestMetricsPropertyProvider.extractValuesFromJSON(RestMetricsPropertyProvider.java:472)

> Based on reading the code, this should be supported by using the # path splitter.
