Review Comment:
Multi-table commit:
1. stage every change: `BaseTransaction.commit` ->
`StagingTableOperations.doCommit`, writes metadata file only, skipping the
locking
2. lock if enabled (HMSLock)
3. verify whether Base metadata location is same as the current table
metadata location
4. batch table properties atomic commit using CAS (NoLock)
5. release locks if any
6. rollback ALL if table has been modified concurrently or exception
