fix bug: mapping from msgpack response to int, Integer, long, Long types works fine

[chabapok]

All of the unit tests of the InfluxDBResultMapper is based on the assumption that all numbers in response from influxd is Double. It will be ok with JSON. But msgpack format is more precise.

So, InfluxDBResultMapper have errors. For example, it throws an exception when mapping number to int, Integer, long, Long types from msgpack responses, but works with json.

This PR fix it (with unit test).

Nice catch, one small formatting nit:

Hi @fmachado, any update on this PR?

I think he stopped working on this a long time ago. That's left a lot of PRs unmerged and most have likely gone to the influxdb-client-java repo.
