Description

Patch adds the following metrics;

• time spent anticompacting data before participating in a consistent repair
• time spent creating merkle trees
• time spent syncing data in a repair
• approximate number of bytes read while creating merkle trees
• number of partitions read creating merkle trees
• number of bytes read while doing anticompaction
• number of bytes where the whole sstable was contained in a repairing range so that we only mutated the repair status
• ratio of how much we anticompact vs how much we could mutate the repair status
• total time spent as a repair coordinator
• total time spent preparing for repair
