                                     boolean forceTCP)
Requests close neighbors from the remote peer. The remote peer may idicate if the data is present on that peer. This is an RPC.

Parameters:

forceTCP - Set to true if the communication should be TCP, default is UDP
Returns:
The future response to keep track of future events
