Generate allure report for review-qa

What does this MR do?

allure-report generation for review-qa tests:

• single test report for review-qa-smoke and review-qa-all tests
• report stored in GCS bucket, doesn't require gitlab artifacts
• screenshot and html attached to specific test directly
• some trend graphs and execution history capabilities

Report for review-qa-smoke: https://storage.googleapis.com/gitlab-qa-allure-reports/gitlab-review-smoke/poc-allure-report/index.html
Report for review-qa-all: https://storage.googleapis.com/gitlab-qa-allure-reports/gitlab-review-all/poc-allure-report/index.html

Next iteration

• Add report links to MR description or comment
• Single report for all tests executed by package-and-qa
• Debug log as attachment to every test case instead of flooding job output?
