This implementation is capable of handling "ASK" and "MOVED" replies
returned by Redis when one of the nodes asks the client for temporary
or permanent redirects of a slot to a different node.
Performances look almost on par with our client-side sharding solution
and everything looks already relatively stable.
Tests are still missing.
The "throw_errors" connection parameter has been removed and replaced by the
new "exceptions" client option since exceptions on -ERR replies returned by
Redis are not generated by connection classes anymore but are thrown by the
client class and other abstractions such as pipeline contexts.
This change does not affect much people using the Predis\Client class (aside
from the different configuration) but gives much more flexibility to those
building their own pieces of code around the internal classes of Predis.
