> HBase provides various metrics through the API's exposed by ScanMetrics class. 
> The JIRA PHOENIX-3248 requires them to be surfaced through the Phoenix Metrics API. Currently these metrics are referred via hard-coded strings, which are not formal and can break the Phoenix API. Hence we need to refactor the code to assign enums for these metrics.
