Implement message queue. This change makes poll handle at most one packet per call, instead of handling all pending packets at once.

'SecondaryEventHandler', used in the secondary role, is now renamed as
PrimaryMasterEventHandler since a secondary is only connected to the primary. On
the other side, the primary apply the SecondaryMasterEventHandler on it's master
connections.
Factorize code in connection(Closed|Timeout)/peerBroken and avoid some checks of 
conditions that can be assume in specialized handlers.
Clean imports and remove some instance checks.

- All incoming connections start with the identification handler which will
apply the right handler depending on the current cluster state and the node
type. So we are now sure that a node is well identified, got an UUID and is
registered into the node manager when it leaves the identification handler.
- During service, clietnt and storage nodes have their own handler

- first, asks which master is the primary
- then, when connected to the primary, request node identification
- then, ask explicitely for partition table and node information, to follow query/answer schema.
Details:
- Master:
 - Move handleAskPrimaryMaster, handleAskNodeInformation and handleAskPartitionTable implementations to base handler to factorise code
 - handleRequestNodeIdentification is not required any more in secondary mode, only handleAskPrimaryMaster
- Client:
 - Make bootstrap handler and master connection behave more similarly to on storage's equivalents
 - Remove PrimaryHandler (moved into PrimaryNotificationsHandler)
 - parse master node configured ip list just once, and register them to node manager just once (in app's __init__)
