Is your proposal related to a problem?

The current behaviour supports skipping primary keys, which are always of serial data type. These are auto-generated by the database. Going forward, serial data type is optional and a user can chose whatever type and name they prefer for the primary key.

Describe the solution you'd like

We should make csv upload behaviour such that:

1. Throw error 'Primary key required for column' if data is missing and the column is not of serial data type
2. For serial data type column, regardless of whether data exists or not within the csv the value should always be autogenerated on the insert

This is currently handled here: https://github.com/ToolJet/ToolJet/blob/develop/server/src/services/tooljet_db_bulk_upload.service.ts
