> Add server level metrics for secondary indexes
> - Histogram metrics for time to complete all secondary index updates per 
> primary table update per index type. Will help us trend perf over time and 
> catch impending issues. 
> - Histogram metrics for number of updates dispatched to secondary index 
> stores to service one primary table update per index type. Will help us catch 
> inefficient behavior or problematic schema design. 
> - Count of deployed secondary indexes by type. Will help understand and trend 
> index usage, or catch deploy of an unwanted index type.
