- 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__)
