HDDS-11105. Generate Robot report in container

[adoroszlai]

What changes were proposed in this pull request?

compose/testlib.sh runs Robot tests in Docker containers. However, it tries to generate test reports locally, which assumes Robot Framework is installed on the host. It fails if rebot is not found, even if all tests pass.

acceptance.sh installs Robot Framework if it's not already available. Therefore it can assume the command rebot is available for report generation.

To simplify local use of acceptance tests, testlib.sh could generate reports in an ozone-runner container, similarly to how tests are executed. Thus we can avoid the need to install Robot Framework.

This worked earlier too right ? I think the test should be to locally run a robot test via test-single.sh

Yes. However GitHub's runner doesn't have Robot Framework installed, we used to install it (install_robot). So the point of my test is to confirm that the report is generated correctly even after removing these installation steps.

I think the test should be to locally run a robot test via test-single.sh
