Multiple stage status or ignore status

## Summary

Original Author: @dkirillov

It would be great to have a way to specify either multiple expected stage statuses or a way to ignore the stage status in an E2E test assertion.

This can be handy when dealing with stages that are influenced by external factors.

## Motivation

We have a lot of terraform plan, terraform apply (skippable) and terraform output modules.

The apply can either succeed or be skipped; depending on the changes in the terraform module. We have to retry it all the time because of this.

## Describe alternatives you've considered

## Additional context

No files or tests are named. Start by locating the E2E assertion handling for stage status, then review how Terraform plan, apply, and output modules report status; define how multiple expected statuses or an ignored status should be specified, and add coverage showing both successful and skipped apply cases are accepted.
