Opt-in a processor token to Signal

When a processor token is not initialized with signal, call /processor/signal/prepare to opt-in that processor token to the data collection process, which will improve the accuracy of the Signal Transaction Score.

If this endpoint is called with a processor token that is already initialized with signal, it will return a 200 response and will not modify the processor token.
