[fix] [test] Fix flaky test ReplicatorTest

[poorbarcode]

Motivation

There are two tests that are not normal operations when using Geo-Replication with a global metadata store, which is should be denied in a production pulsar cluster. they are very dangerous, which leads to a lot of topic deletion and makes namespace policies being incorrect, making other tests in the same class flaky

• Replicatortest.testConfigChange
• ReplicatorGlobalNSTest .testRemoveLocalClusterOnGlobalNamespace

Modifications

• Add a description on the class ReplicatorGlobalNSTest to describe it as the class to run no-normal tests.
• Move Replicatortest.testConfigChange into ReplicatorGlobalNSTest
• Move the normal test ReplicatorGlobalNSTest. testForcefullyTopicDeletion into Replicatortest

Documentation

• doc
• doc-required
• doc-not-needed
• doc-complete

Rename the class ReplicatorGlobalNSTest to ReplicatorGlobalNSDangerousOperationTest

I think this could be handled with a comment instead. Renaming the file will make following changes harder and I don't think that it provides much clarity. Calling something "dangerous" is very vague and always requires further explanation. That's why comments in the test class or in Pulsar documentation are a better approach to tackle this.

Move Replicatortest.testConfigChange into ReplicatorGlobalNSDangerousOperationTest\nMove the normal test ReplicatorGlobalNSTest. testForcefullyTopicDeletion into Replicatortest

Makes sense

@poorbarcode I disabled one problematic test causing OOME in #22586 . Would it be fine to include the revert in this PR or is it better to handle that separately?

LGTM

I will review the test testWriteMarkerTaskOfReplicateSubscriptions that #22586 disabled later, and push another PR to fix the flaky issue
