Refine submission tables to hide unnecessary columns and reduce complexity.

Is your feature request related to a problem? Please describe.
On submission table page, we provide users will long columns will all the details. While some column are important, some are redundant and need not be include on table view. The fields like warmup features and other columns doesn't make sense to users on the first look. If they want to view everything, they can go to submission details page.

Describe the solution you'd like
Remove all unneccessary fields from submission table and only show the details that are useful for users on the first look. This way we can create less complex table with only important details.
Following fields can be removed:
Email -> since we don't get the email for now.
Instructions, warmup (only providing coordinate doesn't make much sense), feature, new feature, status (saying status=2 doesn't make much sense to project managers, may be we can add what status 2 means otherwise remove it)
