Review Comment:
Add files will do this InMemoryFileIndex calculation twice (first it will do
here to infer the spec with option.empty()) and later it will be called in
getPartitions (see L902) to list the files. I assume since fileStatusCache is
passed with same spark session it will not do recomputation?
Else I will calculate the InMemoryFileIndex in AddFilesProcedure and infer
schema there, and pass it along to getPartitions()
