All option classes have been moved in the Predis\Configuration\Option
namespace and some have been optimized to have less impact on client
initialization timings.
Furthermore the accepted values for some options have been changed,
this is the complete list of accepted values:
- _aggregate_: callable returning an aggregate connection.
- cluster: string value ("predis", "redis"), callable returning an
aggregate connection.
- replication: string value ("predis", "sentinel"), callable returning
an aggregate connection.
- commands: command factory, named array mapping command IDs to PHP
classes, callable returning a command factory or a named array.
- connections: connection factory, callable returning a connection
factory, named array mapping connection schemes to PHP classes.
- _prefix_: string value, command processor, callable.
- _exceptions_: boolean value.
Note that the cluster and replication options now return a closure
acting as initializer instead of an aggregate connection.
