/**
@brief Either send or enqueue a response to a client, optionally with a completion notice.
@param ctx Pointer to the method context.
@param data Pointer to the response, in the form of a jsonObject.
@param complete Boolean: if true, we will accompany the RESULT message with a STATUS
message indicating that the response is complete.
@return Zero if successful, or -1 upon error.
For an atomic method, add a copy of the response data to a cache within the method
context, to be sent later. In this case the @a complete parameter has no effect,
because we'll send the STATUS message later when we send the cached results.
If the method is not atomic, translate the message into JSON and append it to a buffer,
flushing the buffer as needed to avoid overflow. If @a complete is true, append
a STATUS message (as JSON) to the buffer and flush the buffer.
