CLUSTER SLOTS returns a structured response easier to handle compared
to the bulk response of CLUSTER NODES which must be parsed making the
whole thing more fragile.
CLUSTER SLOTS has been added in Redis 3.0.0b7.
This is more consistent with the actual purpose of this method and
more in-line with a possible future change in the underlying command
used to retrieve the slots map if redis-cluster will implement the
CLUSTER SLOTS command.
* Renamed SingleConnectionInterface to NodeConnectionInterface since
this name is better and makes even more sense in the context of
cluster and replication scenarios.
* Moved specialized aggregate connections (the ones implementing both
predis and redis cluster and master/slave replication) in a newly
created Predis\Connection\Aggregate sub-namespace.
* Removed the "Connection" part from names of aggregate connection
interfaces in the Predis\Connection\Aggregate sub-namespace.
* Changed "Composable" to "Composite" in the name of interfaces and
classes that can use pluggable protocol processors.
