Initialize StringBuilder in Slf4jReporter with estimated size

    Details

      Description

      The Slf4jReporter uses a StringBuilder to generate the report that is later logged. Currently we don't pass the initial size, which for large deployments can result in frequent resizing of the backing array.

      We could either estimate the expected size based on the # of metrics, or store the size of the last report (given that the total metrics space is fairly constant).
