[BUG] OpenSearch-Dashboards integTest does not uninstall OpenSearch after completion

[peterzhuamazon]

Hi,

When running the OSD integTest through Python, both OS and OSD will be installed.
But when completing the test or failed the test, only OSD will be uninstalled.

The logic here should be finetuned, this is only for DEB/RPM, not for TAR due to how uninstall function is being written:
https://github.com/opensearch-project/opensearch-build/blob/main/src/test_workflow/integ_test/distribution_rpm.py#L56
https://github.com/opensearch-project/opensearch-build/blob/main/src/test_workflow/integ_test/distribution_deb.py#L54

Thanks.

def start(self) -> None:
        os.makedirs(self.work_dir, exist_ok=True)

        self.all_services = [self.service] + self.dependencies

        for service in self.all_services:
            service.start()

        for service in self.all_services:
            service.wait_for_service()

We might able to retrieve the above service list and run the uninstall based on that.
In src/test_workflow/test_cluster.py
