The comment is no longer valid. The constructor can be completely removed, we can rely on the default one.

This and other existing methods that are not going to be overridden can still be static.

Let's define public abstract FileSystem getFs() in the parent class (implementations already exist, just add @Override). This way we don't need to add a template method for each FileSystem operation (like listStatusIterator(Path)) in the tests.

As a sub-task of HDDS-12355, I converted
OzoneFileSystemTeststo abstract class (previously it was static final) and renamed it toOzoneFileSystemTestBase. This enables template method pattern and abstracts similar tests betweenAbstractOzoneFileSystemTestandAbstractRootedOzoneFileSystemTesteasier.This PR also addresses:
testOzoneFsServiceLoaderfrom both test classes becauseFileSystem.getFileSystemClass()is Hadoop's code, not Ozone's. We should test our implementation, not the framework's behaviortestCreateKeyWithECReplicationConfigandtestListStatusIteratorWithDirtoOzoneFileSystemTestBaseclass.setPageSizemethod to a new classOzoneFileSystemTestUtilsfrom oldOzoneFileSystemTests.Since there are a lot of duplicates in the two test classes, subsequent Jira tickets will continue to evaluate other duplicate tests if this approach is accepted.
