Setup helper for testing with protest
Add Ruster::Node
Add Ruster::Node#enabled?

Indicates if a redis server is enabled as a cluster node.
Read info line as sent by CLUSTER NODES
Parse slots information

Note that migrating/importing slots aren't being parsed at the moment.
Add Ruster::Util
Use Util#parse_info for Node#enabled?
Fix typo
Parse migrating/importing slots
Ignore comments in INFO parsing
Refactor Node tests
Add Node#to_s
Refactor node information tests
Create node from info line

This will be useful for when running in a real cluster.
Proper cleanup of redis-server when test ends
Load node(s) information from cluster
Meet nodes
Wrap client calls with error checking
Forget nodes

A tragic love story...
We're using protest for testing, not cutest
