Make it simpler to call NEOCluster.__newProcess.
Categorise process by node type, and add accessors to retrieve all nodes of a given type.
Generate node uuids in the test and implement accessors for this.

Decorators defined in decorators.py are no more used in NEO, all extracted
patterns are now implied by the handlers.

Add the possibility to provide a UUID to a node upon startup. Mostly usefull in functional tests where we want to map a process to its UUID.

- SERIAL_NOT_FOUND is no more usefull.
- TIMEOUT_ERROR_CODE/handleTimeoutError is not used.

consistent with other handler methods.
Remove the handleSerialNotFound method because it's never used.

When the disconnection is not caused by a broken node event, pick the state from a mapping: by default, a disconnected node is considered down (ie, removed from node manager as soon as it gets disconnected), with the exception of a storage node (it must be kept in partition table, so it must also be kept in node manager).

Do not silently ignore an unknown node in disconnection handler method. Any node being disconnedted at the level of this handler must be known, otherwise it's a bug.

Make count_dict property always contain all nodes, even if they are registered for the first time in FEEDING state.
This fixes the annoying KeyError raised in log method when it happens.
