   ## How was this patch tested?
   Verified locally using below steps:
   
   1. Create bucket bucket1
   2. Delete bucket bucket1 (Before Apply transaction) 
   3. Create key key1 inside bucket1 (Pre execute) 
   4. Delete bucket bucket1 (Apply transaction)
   5. Key1 create(During apply transaction)
   Calls `OzoneManagerRatisUtils.createClientRequest` which uses [getBucketLayout](https://github.com/apache/ozone/blob/e374aae82db1f39e666325d47fcd09a0392d0b70/hadoop-ozone/ozone-manager/src/main/java/org/apache/hadoop/ozone/om/request/BucketLayoutAwareOMKeyRequestFactory.java#L230)
   Since bucket is already deleted, it throws [Bucket Not Found](https://github.com/apache/ozone/blob/e374aae82db1f39e666325d47fcd09a0392d0b70/hadoop-ozone/ozone-manager/src/main/java/org/apache/hadoop/ozone/om/OzoneManagerUtils.java#L143)
   Ozone manager [terminates](https://github.com/apache/ozone/blob/e374aae82db1f39e666325d47fcd09a0392d0b70/hadoop-ozone/ozone-manager/src/main/java/org/apache/hadoop/ozone/om/ratis/OzoneManagerStateMachine.java#L572) as it doesn't handle OMException.
   
   After fix It fails normally and ozone manager doesn't stop, And returns error message to client.
