SERVER-55556 add new totalUnitsWritten metric; add new localTime field to operationMetrics output

totalUnitsWritten is a metric that represents the number of bytes written to a document plus any index entries that follow, prior to writing another document; these bytes are then translated into Units as per the totalUnitWriteSizeBytes parameter.
Additionally, a new field localTime will now appear in every BSONArray (per database) included in the $operationMetrics aggregation stage
