/**
* Adds a delta to the PNCounter value. The delta may be negative for a
* subtraction.
*
* The invocation will return the replica timestamps (vector clock) which
* can then be sent with the next invocation to keep session consistency
* guarantees.
* The target replica is determined by the {@code targetReplica} parameter.
* If smart routing is disabled, the actual member processing the client
* message may act as a proxy.
