Unaccessible node removal does not seem to work correctly

The sendMessage method for binary data payload knows to remove the node from the ring however all JSON related admin methods do not execute the same logic to remove unaccessible node thus in hconsole when data and admin clients were separately created, the admin client keeps hitting the off line node even when it has previously failed connecting to the node

After further investigation I found the problem is actually in the algorithm used to pick a random node for admin requests since the initial seed server list was never updated for the client it ends up picking the offline node. The client should update the seed server list after getting the full picture from the seed server initially.
