'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__)
