 payload_server should be equipped with a threshold. When chopper asks for
 a payload for specific chop block, payload_server should checks each
 available payload candidate upon the block size, computes the resulting
 overhead and if the overhead exceed the threshold, should be omitted from
 the list.

 Current behaviour is as follows:

 payload_server choose randomly N payloads and stops when it finds m
 payloads all with higher capacity than chopper requested. Then the
 smallest of this list will be chosen for transmission.

 This should be changed in a way that capacity > chopper's requested
 shouldn't be the only criterion to go on the m-short list but also the
 overhead should be less than the threshold.
