middleware/monitoring: add more monitoring (#182)

Browse source 
* Split response size into normal responses and AXFR|IXFR responses.
* Split out incoming sizes as well in normal and AXFR|IXFRs.
* Add meta qtype to the monitored qtypes.
* Make duration to be exported in milliseconds instead of seconds.
