The stats API broadcasts requests to all nodes and renders node responses using toXContent. For the local node, the stats API's calls toXContent on the node response directly. For remote node, the coordinating node gets a serialized content from ADStatsNodeResponse.writeTo, deserializes the content and renders the result using toXContent. ADStatsNodeResponse.writeTo uses StreamOutput::writeGenericValue that only recognizes built-in types (e.g., String or primitive types). It throws exceptions for types such as java.time.Instant and Entity. This PR fixes the bug by converting non-built-in types to built-in types in node stats response. This PR also removes model id from Entity.toString as it is random across different runs and keeps only attributes. This can help locate the same node in hash ring. Testing done: * Verified stats API response on a multi-node cluster for a multiple-category field detector. * Added unit tests.

Description
The stats API broadcasts requests to all nodes and renders node responses using toXContent. For the local node, the stats API's calls toXContent on the node response directly. For remote node, the coordinating node gets a serialized content from
ADStatsNodeResponse.writeTo, deserializes the content and renders the result using toXContent. ADStatsNodeResponse.writeTo uses StreamOutput::writeGenericValue that only recognizes built-in types (e.g., String or primitive types). It throws exceptions for types such as java.time.Instant and Entity. This PR fixes the bug by converting non-built-in types to built-in types in node stats response.
This PR also removes model id from Entity.toString as it is random across different runs and keeps only attributes. This can help locate the same node in hash ring.
This PR also removes unused fields in ADStats.
