implementations of this interface must be thread-safe.", regarding the space 
full check and space reservation, it can be done as an atomic operation in the 
chooseVolume internally, so that there will no over allocation of space due to 
concurrent container creation and container import.`
   
   I think that requires: [HDDS-12556. Use closable handle to allocate and 
release committed bytes](https://issues.apache.org/jira/browse/HDDS-12556), as 
currently VolumeChoosingPolicy just select and return a volume, and the real 
allocate part isn't its scope. Making it synchronize would just prevent race 
condition on the volumeList.
