Sounds good, doesn't work.
Actually, band->SetMetadataItem("NETCDF_VARNAME","somename...") does not 
raise any error and I tracked with a debugger that it goes down to  
GDALMultiDomainMetadata::SetMetadataItem() and really calls 
CPLStringList::AddNameValue(),

but when reading the saved dataset file created by the netCDF driver, 
SUBDATASET_<i>_NAME are still "netcdf:<file>:Band1, Band2..."

I am still investigating to see if it might be related to the wrong 
domain, but so far I can't tell.
