This commit fixes#5570. It is a similar bug to one fixed a few weeks
ago and is due to the range API to be called with NULL as "end ID"
parameter instead of repeating again the start ID, to be sure that we
selectively issue the entry with a given ID, or we get zero returned
(and we know we should emit a NULL reply).
This fixes the issue reported in #5570.
This was fixed the hard way, that is, propagating more information to
the lower level API about this being a request to read just the history,
so that the code is simpler and less likely to regress.

slot is unassigned before ADDSLOTS
- clusterManagerFixSlotsCoverage: after cold
migration, the slot configuration
is now updated on all the nodes.

This bug had a double effect:
1. Sometimes entries may not be emitted, producing broken protocol where
the array length was greater than the emitted entires, blocking the
client waiting for more data.
2. Some other time the right entry was claimed, but a wrong entry was
returned to the client.
This fix should correct both the instances.

server.hz was uninitialized between initServerConfig and initServer.
this can lead to someone (e.g. queued modules) doing createObject,
and accessing an uninitialized variable, that can potentially be 0,
and lead to a crash.
