Allow NetCDF unit library configuration, and fix regression with some outputs caused by unit library upgrade

Issue Type:	Bug
Assignee:	Andrea Aime
Components:	Main, NetCDF
Created:	26/Sep/18 6:46 PM
Priority:	Medium
Reporter:	Andrea Aime

The current code gets the unit for each band from the read and formats it using its own “toString()” method, which internally uses a formatter. During NetCDF encoding it has then to parse such string back to a unit, but the uom library we are using nowadays cannot do so reliably: https://github.com/unitsofmeasurement/uom-se/issues/201 The long term fix will eventually require an overhaul of the unit libraries we use, but for the time being, a formatter that properly round-trips has been added in GeoTools. At the same time, allow the configuration of NetCDF unit management via config files.
