Fix Flaky Test: AppBalanceSelectStorageStrategyTest#selectStorageTest

[smallzhongfeng]

What changes were proposed in this pull request?

When testing, close the scheduler thread detectStorageScheduler.

Why are the changes needed?

When testing, in order to ensure that multiple paths are normal, the method of manually scheduling detectStorage is used.

applicationManager.getRemoteStoragePathRankValue().get(remotePath1).getCostTime().set(0);
applicationManager.getRemoteStoragePathRankValue().get(remotePath2).getCostTime().set(0); 

The original repair may still fail to write the hdfs file later.

Does this PR introduce any user-facing change?

No.

How was this patch tested?

origin uts.
