Allure plugin for Gitlab CI/CD

**Is your feature request related to a problem? Please describe.**
We use Gitlab CI/CD for running autotests (Java + TestNG + Selenide) as we have requirements for this. But in gitlab the only thing I was able to do is to create inside docker image allure report and attach it to job run as zip archive. Then you should download it and open locally. Using allure in such way doesn't allow us to have execution trend at all as far as we have to do some magic with all browsers to see it with its jsons. I was searching an option to do it in gitlab itself (for example using their html view) and there is no option also.

this is part of my *.yml file.
`after_script:
- cd qa-tests
- mvn allure:report
artifacts:
when: always
name: "Report"
paths:
- $CI_PROJECT_DIR/qa-tests/target/site/allure-maven-plugin/
expire_in: 15 days`

**Describe the solution you'd like**
to create a plugin for gitlab as for Jenkins to have all allure features and the option to see reports inside gitlab without downloading reports and serving them on separate server.

No repository file or test is named in the issue. Start with the GitLab CI/CD .yml snippet and the Jenkins integration referenced in the request, then determine how Allure reports and execution trends could be rendered inside GitLab; done means a working GitLab plugin that avoids downloading reports or serving them separately.
