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.

- Add expect* methods, to allow continuing as soon as a condition is encountered.
- Define master node count as a constant.
- Make getMasterNodeList able to filter on node state.

When primary master node gets disconnected, use NodeManager.update method with DOWN_STATE, so that it gets removed.
Clear node manager content and re-add all master node given in the configuration before trying to reconnect to primary master.

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).

ensure no more than one master could run concurrently when they restart without
known each other.

Make connection.py call connectionAccepted with the new connection as parameter.
Change connectionAccepted prototype, as fewer parameters are needed now that "conn" contains them.

Apply SecondaryMasterHandler to all established connections after having set the identificationHandler on the listening connection.
This fixes primary master node not notifying secondary master node disconnections.

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).

It is only important to raise a type error when other's type might be equal to EnumItem. In other cases, just return False.

- 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.
