   ### Step 1
   Current fragment_mgr use 
   https://github.com/apache/incubator-doris/blob/0430714ca9b0d910ba9b290276da05adfc752f8f/be/src/runtime/fragment_mgr.cpp#L461-L463
   to avoid ThreadPool::offer() failed. If we replace it with kudu thread pool, we must handle this situation:
   ```exec_state created -> prepare ->  submit to thread pool failed (means never execute)-> destory```
   
   I'll force fragment_mgr to use thread pool ( not create pthread) to test it. No need to replace thread pool firstly.
