* initial work done to FreeBSD NFS pollers for JSON support
* minor formatting cleanup and no longer pass update_application a array for the second argument
* add test data and snmprec(minus legacy)
* use variables from the data part of the JSON in the metrics
* add the legacy snmprec file for fbsdnfsserver
* add the most of the test stuff for FreeBSD NFS
* add the legacy SNMP data for FreeBSD NFS client
* add the missing "applications": {
* properly rename the tests to match the appname
* correct the appname stuff in the tests
* make a chunk of the json properly a array item
* correct this to the actual value
* change 0 to 0.0 for one and make quote data
* hmm... RdirPlus is becoming Rdirplus
* whoops, revert that... should be RdirPlus as that is what is returned
