Add a 'outputTableName' argument to support custom sample names

[jeffdesc]

Description of the changes

All results of all service checks are being added to the "NagiosServiceCheckSample", but in most situations you want to split this up to have custom samples per service check. This way you can structure your data in New Relic Insights properly.

This code is in use in a forked version in our monitoring system and has been tested, it's been working as expected.

However on every major code change, I've to re-create a patch which creates too much hassle. This way it can be pushed into the NRI Nagios code base.
