Make config lookups case insensitive

The product names in config can be spelled in various and confusing
ways. Make the lookups not care about case.

Ideally this should use `casefold`, but that is only available since
Python 3.3. However the product names will almost certainly be ASCII
only.

Fixes: NEXUS-252
