Description

Since the Ratis metrics work is going on in parallel from multiple folks, it will be a good idea to have a final sanity check and cleanup tasks to bring the task to closure. These are the tasks aimed in this JIRA.

• Organize RatisMetrics and RatisMetricNames into a single class
  (It would be good to organize RatisMetrics and RatisMetricNames into a single class. The metrics can be organized like RaftServerConfigKeys and RaftClientConfigKeys so that metrics corresponding to a particular component like Log, Appender can be tracked in a sub class)
• Investigate whether we can move the groupId and followerId in metric names to attributes. This will make aggregation from a metrics system easier.
• Deploy a cluster and do sanity check of all metrics.
