File Upload: Allow users to skip ingest as tabular data.

[kcondon]

In v3.6 we had an upload as "other" option that allowed problematic files, those failing ingest or too large to ingest, to upload as the original format without additional processing.

We might want to call it something else rather than "other" but this is a very useful feature for Support and users too.

I just wanted to point out the the File Import Batch job in support of rsync being work on in #3353 currently bypasses all the extra processing.
