Add metadata automatically from phenofront/phenodata metadata #1867
Description
Is your feature request related to a problem? Please describe.
I am always surprised that I have to list metadata terms in config.filename_metadata when the metadata is not in the filename but is in a metadata.json (or snapshotinfo.csv) file.
Describe the solution you'd like
I'd like those terms to be automatically added to the config.filename_metadata list.
Describe alternatives you've considered
It's possible that this is a lot of extra metadata, I don't really think that is a problem but we could have a greedy flag or something to turn off this behavior if you really don't want more metadata or are trying to exclude some (although I don't know why that would be).
