Update pipeline to use vat import api instead of direct SQL update

This template is ONLY used for enhancement requests. Bug reporting or new feature request issues should use the other template options for issue submission.

Current Behavior

The pipeline uses sql directly with the vat db to add/update findings for each container.

Purpose

Use the vat import api to help VAT team with issue remediation and move away from using SQL directly. Testing for this has already been completed in #307 (closed)

Plan

• Wait for sidecars to be deployed for pipeline runners in https://repo1.dso.mil/platform-one/private/big-bang/ironbank/ironbank-bootstrap/-/issues/458
• Final review and approval of Cody's MR !552 (merged)
• Merge Cody's MR
• Keep in review for a couple days in case there are unanticipated issues.

Acceptance Criteria

• VAT import api is used in pipeline instead of a direct SQL insert/update
