David Roberts d5baedb789 [ML] Change dots in CSV column names to underscores (#42839)
Dots in the column names cause an error in the ingest
pipeline, as dots are special characters in ingest pipeline.
This PR changes dots into underscores in CSV field names
suggested by the ML find_file_structure endpoint _unless_
the field names are specifically overridden.  The reason for
allowing them in overrides is that fields that are not
mentioned in the ingest pipeline can contain dots.  But it's
more consistent that the default behaviour is to replace
them all.
