Daniele Alessandri 43a6ae181e Fetch updated slots map from node indicated by -MOVED response.
This optimization makes it possible to fetch the slots map directly
from the server indicated by the -MOVED response eliminating the need
to use a random node in the pool, which in turn could require Predis
to open a new and useless connection.
