scripted-diff: [net processing] Rename PeerLogicValidation to PeerManager

-BEGIN VERIFY SCRIPT-
sed -i 's/PeerLogicValidation/PeerManager/g' $(git grep -l PeerLogicValidation ./src ./test)
sed -i 's/peer_logic/peerman/g' $(git grep -l peer_logic ./src ./test)
-END VERIFY SCRIPT-

PeerLogicValidation was originally net_processing's implementation to
the validation interface. It has since grown to contain much of
net_processing's logic. Therefore rename it to reflect its
responsibilities.
