 DeltaDiscoveryRequest and DeltaDiscoveryResponse are used in a new gRPC
 endpoint for Delta xDS.

 With Delta xDS, the DeltaDiscoveryResponses do not need to include a full
 snapshot of the tracked resources. Instead, DeltaDiscoveryResponses are a
 diff to the state of a xDS client.
 In Delta XDS there are per-resource versions, which allow tracking state at
 the resource granularity.
 An xDS Delta session is always in the context of a gRPC bidirectional
 stream. This allows the xDS server to keep track of the state of xDS clients
 connected to it.

 In Delta xDS the nonce field is required and used to pair
 DeltaDiscoveryResponse to a DeltaDiscoveryRequest ACK or NACK.
 Optionally, a response message level system_version_info is present for
 debugging purposes only.

 DeltaDiscoveryRequest plays two independent roles. Any DeltaDiscoveryRequest
 can be either or both of: [1] informing the server of what resources the
 client has gained/lost interest in (using resource_names_subscribe and
 resource_names_unsubscribe), or [2] (N)ACKing an earlier resource update from
 the server (using response_nonce, with presence of error_detail making it a NACK).
 Additionally, the first message (for a given type_url) of a reconnected gRPC stream
 has a third role: informing the server of the resources (and their versions)
 that the client already possesses, using the initial_resource_versions field.

 As with state-of-the-world, when multiple resource types are multiplexed (ADS),
 all requests/acknowledgments/updates are logically walled off by type_url:
 a Cluster ACK exists in a completely separate world from a prior Route NACK.
 In particular, initial_resource_versions being sent at the "start" of every
 gRPC stream actually entails a message for each type_url, each with its own
 initial_resource_versions.

    • getResourceNamesSubscribeList

      public com.google.protobuf.ProtocolStringList getResourceNamesSubscribeList()
       DeltaDiscoveryRequests allow the client to add or remove individual
 resources to the set of tracked resources in the context of a stream.
 All resource names in the resource_names_subscribe list are added to the
 set of tracked resources and all resource names in the resource_names_unsubscribe
 list are removed from the set of tracked resources.

 *Unlike* state-of-the-world xDS, an empty resource_names_subscribe or
 resource_names_unsubscribe list simply means that no resources are to be
 added or removed to the resource list.
 *Like* state-of-the-world xDS, the server must send updates for all tracked
 resources, but can also send updates for resources the client has not subscribed to.

 NOTE: the server must respond with all resources listed in resource_names_subscribe,
 even if it believes the client has the most recent version of them. The reason:
 the client may have dropped them, but then regained interest before it had a chance
 to send the unsubscribe message. See DeltaSubscriptionStateTest.RemoveThenAdd.

 These two fields can be set in any DeltaDiscoveryRequest, including ACKs
 and initial_resource_versions.

      repeated string resource_names_subscribe = 3;
      Specified by:

    • getResourceNamesSubscribeCount

      public int getResourceNamesSubscribeCount()
       DeltaDiscoveryRequests allow the client to add or remove individual
 resources to the set of tracked resources in the context of a stream.
