Nagios parser does not support ranges in performance data

[danielnelson]

Bug report

The nagios parser does not support ranges in the performance data. Ranges are
used with the critical and warning fields, there is more detail in this documentation: https://nagios-plugins.org/doc/guidelines.html#AEN200

Relevant telegraf.conf:

[[inputs.exec]]
  commands = ["cat nagios"]
  data_format = "nagios"

$ cat nagios
OK: Load average: 0.00, 0.01, 0.05 | 'load1'=0.00;0:4;0:6;0; 'load5'=0.01;0:3;0:5;0; 'load15'=0.05;0:2;0:4;0;

System info:

Telegraf 1.6.1

Steps to reproduce:

1. telegraf --input-filter exec --test

Expected behavior:

The range data should be encoded in some form, there are a few options:

Use _lt, _gt, _le, _ge as less than, greater than, less than or equal,
and greater than or equal:

> nagios_state_centreonplugins state=0i 1525116499000000000
> 'load1'_centreonplugins min=0,value=0,warning_lt=0,warning_gt=4,critical_lt=0,critical_gt=6 1525116499000000000
> 'load5'_centreonplugins min=0,value=0.01,warning_lt=0,warning_gt=3,critical_lt=0,critical_gt=5 1525116499000000000
> 'load15'_centreonplugins min=0,value=0.05,warning_lt=0,warning_gt=2,critical_lt=0,critical_gt=4 1525116499000000000

Put the range unaltered as a tag, this could be acceptable if the value changes infrequently and does not need graphed.

> nagios_state_centreonplugins state=0i 1525116499000000000
> 'load1'_centreonplugins,warning=0:4,critical=0:6 min=0,value=0 1525116499000000000
> 'load5'_centreonplugins,warning=0:3,critical=0:5 min=0,value=0.01 1525116499000000000
> 'load15'_centreonplugins,warning=0:2,critical=0:4 min=0,value=0.05 1525116499000000000

Actual behavior:

> nagios_state_centreonplugins state=0i 1525116499000000000
> 'load1'_centreonplugins min=0,value=0 1525116499000000000
> 'load5'_centreonplugins min=0,value=0.01 1525116499000000000
> 'load15'_centreonplugins min=0,value=0.05 1525116499000000000
