Additional column options

[sbliven]

It would be useful to have additional columns exposed in the main list:

• owner
• ownerEmail
• contactEmail
• Ingestion date (I think this is "createdAt", but the date fields always confused me)
• PID

It would also be nice to search/filter by these criteria. If most SciCat users don't need these columns they can be hidden by default behind the 'Table Settings' menu.

For our use cases we ingest data manually. This means that the ingestion date can be significantly after the file timestamps, and users may expect to see their most recent ingestion on the first page. We also have many users who ingest data under the same group, so filtering by user is important.
