FrostFS storage nodes implement variation of EigenTrust iterative algorithm to calculate some metric for every peer. This metric should be distributed to the inner ring nodes so they can remove 'bad' from the network map.

We had some issues with this implementation:

algorithm works not so very well in with isolated nodes,
it produces a lot of network code in storage node,
it is not accurate enough to remove nodes from the network map.

Describe the solution you'd like

Remove reputation messages and service from the protocol
Remove reputation collection from the node

This is an issue from the series of incompatible protocol changes. The purpose of these changes is to rework some FrostFS protocol mechanisms which were non-demanding for the users in private and public networks or they provide unnecessary complexity in the protocol and its implementation. ## Is your feature request related to a problem?
