Make all election handler classes inherit from ElectionHandler: master will send a notification to all nodes that a new master appeared, which includes the new master itself, so it must expect a NotifyNodeInformation packet.

Add extra checks when stopping primary master: now check that current primary master is None before expecting a new one to appear.

Hence, don't add non-running nodes to unconnected_master_node_set before each election attempt.
Preserve negotiating_master_node_set between attemps to reuse possibly pending connections.

When primary master node gets disconnected, use NodeManager.update method with DOWN_STATE, so that it gets removed.

PrimaryMasterHandler must not be applied to the listening connection, but only to the one remaining client connection (ie, the connection we established to the primary master node).
All other connections (listening & server) must get IdentificationHandler (actualy only using handleAskPrimaryMaster, so a more restricted handler would better fit).

Change connectionAccepted prototype, as fewer parameters are needed now that "conn" contains them.

Instead of stopping the whole cluster, only stop masters. This avoids disconnecting neoctl from admin process, as it will not reconnect (to be tested separately).

- Fix an inversion in killSecondaryMaster making it kill only primary nodes.
- Add DELAY_SAFETY_MARGIN to make explicit which part of a sleep delay is just here for safety, WRT the "mandatory" part of the delay.
- A disconnected secondary master node must be removed from NM, so its state becomes None.
- Add tests comparing the behaviour of a 2-masters and 3-masters cluster.
