794d3401e9 Cluster: Restore proper trib master iteration 
This got removed in 15ef91e during a new feature addition.

The prior commit had "break if masters.length == masters_count"
but we are guaranteed to aready have that condition met since
otherwise we would haven't gotten this far.

Without this break statement, it's possible some masters may
be forgotten and have zero replicas while other masters have
more than their requested number of replicas.

Thanks to carlos for pointing out this regression at:

18dafd646a redis-trib: call MIGRATE via r.client.call as fix for redis-rb API changes. 
See issue #1593.

Thanks to @badboy for suggesting the direct client.call fix.

5604970426 redis-trib: new subcommand 'call'. Exec command in all nodes. 
Example:

./redis-trib.rb call 192.168.1.11:7000 config get cluster-node-timeout
 2014-03-11 14:58:55 +01:00

15ef91eb7b 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.

e4732138b0 Cluster: redis-trib fix: cover new case of open slot. 
The case is the trivial one a single node claiming the slot as
migrating, without nodes claiming it as importing.

b1d3dd657d Cluster: use an hardcoded 60 sec timeout in redis-trib connections. 
Later this should be configurable from the command line but at least now
we use something more appropriate for our use case compared to the
redis-rb default timeout.

e9384bb846 redis-trib: All output wrapped by a specific function. 
This is needed in order to colorize it as next step.
We use conventions in output messages such as

>>> This is an action
*** This is a warning
[ERR] This is an error
[OK] That's fine

And so forth, so that a color will be associated checking the first
three chars.
