Refactor jobs tab to Vue/GraphQL

What does this MR do and why?

This is the First MR:

• Introduces jobs_tab_vue feature flag for safety
• Updates the jobs tab on the pipeline view to use Vue/GraphQL.
• Introduces infinite scrolling instead of loading all jobs at once
• Makes the columns dynamic for custom rendering for different use-cases

The second MR will add feature tests with the feature flag on.

Another MR is underway that will return the jobs in the correct order
