Michal Niewrzal 98f4f249b2 satellite/overlay: refactor KnownReliable to be used with repairer
Currently we are using KnownUnreliableOrOffline to get missing pieces
for segment repairer (GetMissingPieces). The issue is that now repairer
is looking at more things than just missing pieces (clumped/off
placement pieces).

KnownReliable was refactored to get data (e.g. country, lastNet) about
all reliable nodes from provided list. List is split into online and
offline. This way we will be able to use results from this method to all
checks: missing pieces, clumped pieces, out of placement pieces.

This this first part of changes to handle different kind of pieces in
segment repairer.
