Alerts for Redis unavailability

[msavin]

It would be cool if this package created some kind of publication or something to notify clients if Redis is unavailable. Ideally, we could run something like Meteor.hasRedis and notify end-users of issues if there are any.

Additionally, maybe create room for a callback:

RedisOplog.onRetry(function (retryCount) {
  if (retryCount > 5) {
    panic();
    callMom();
    disruptCEOMeditationSession();
  }
})

@msavin this is going to be fixed in the 1.2.3 release I already did it.
