Release Announcement: Telegraf 1.18.2

Telegraf 1.18.2 has been released as a maintenance update with several improvements. The JSON format now supports null values for successful detection and returns an empty metric without errors. The common.shim has been updated to accept larger inputs from the scanner, while the APCUPSD Input plugin resolves an ALARMDEL bug in a forked repository. Other updates include support for float64 in Converter Processor, NFS Client Input, SNMP Input, Sumo Logic Output, and VMware vSphere Input. The MetricLookback setting has been added to handle reporting delays in vCenter 6.7 and later. OPC UA Client Input error handling has also been fixed.
