  feature

• What is the current behavior? (You can also link to an open issue here)
  Every consumer can report a provider as unresponsive. If a provider has enough complaints, he's punished (unstaked).

• What is the new behavior (if this is a feature change)?
  The problem with the current behavior is that a group of very small consumers could potentially take down a large provider. The new design punishes providers in correlation with the CU they serviced.
  To check whether a provider should be punished (jailed/unstaked), we compare the CU serviced by the provider to the used CU of the complainers (the CU that would have used with this provider, but couldn't since he was unresponsive). Only if the complainers' CU is larger than the provider's serviced CU, the provider gets punished.

• Please describe what manual tests you ran, if applicable
  I've modified the current unresponsive unit tests and added sort of a stress test to measure the amount of time the check for unresponsive providers (and punishment) takes

Note that the unresponsive stress test is very slow, so we might omit it after we get the timing results (its goal is to test how much time the unresponsive provider check takes, since it happens every epoch)
