Add support for .HAR file to integrated load testing

Problem to solve

As a tester, I want to use a recording in .har format to replicate load testing, so that I can trust real customer journeys will be performant under load.

Intended users

• Sasha (Software Developer)
• Simone (Software Engineer in Test)

User experience goal

A user can include a .har file with their load testing setup to run that journey without using a converter.

What does success look like, and how can we measure that?

What is the type of buyer?

Is this a cross-stage feature?

Original writeup

Depending on the tool selected for https://gitlab.com/gitlab-org/gitlab-ee/issues/3016, we made add a library that has support for .HAR archive files as a method for replaying "real world" transactions against an application that will more closely create realistic load tests based on organic use of a given application.

As a follow up to https://gitlab.com/gitlab-org/gitlab-ee/issues/3016 we should consider exposing first class support for this type of load testing as an addition to this feature.
