Adapt CloseFollowerIndexIT for replicated closed indices (#38767)
Now the test `CloseFollowerIndexIT` has been added in #38702, it needs to be adapted for replicated closed indices. The test closes the follower index which is lagging behind the leader index. When it's closed, no sanity checks are executed because it's a follower index (this is a consequence of #38702). But with replicated closed indices, the index is reinitialized as a closed index with a `NoOpEngine` and such engines make strong assertions on the values of the maximum sequence number and the global checkpoint. Since the values do not match, the shards cannot be created and fail and the cluster health turns RED. This commit adapts the `CloseFollowerIndexIT` test so that it wraps the default `UncaughtExceptionHandler` with a handler that tolerates any exception thrown by `ReadOnlyEngine.assertMaxSeqNoEqualsToGlobalCheckpoint()`. Replacing the default uncaught exception handler requires specific permissions, and instead of creating another gradle project it duplicates the `internalClusterTest` task to make it work without security manager for this specific test only. Relates to #33888
