redis-trib: create subcommand is now able to assign spare slaves.
redis-trib: create subcommand is now able to assign spare slaves.

Example: if the user will try to configure a cluster with 9 nodes,
asking for 1 slave for master, redis-trib will configure a 4 masters
cluster with 1 slave each as usually, but this time will assign the
spare node as a slave of one of the masters.
