That’s a great job ~
It seems to be satisfied our requirement very well.
Omega and Alpha can be integrated with TCC, it looks like:
1. Begin transaction，alpha generate txid
2. Main service invoke try method of sub service.
omega would register confirm and cancel method to alpha binding with
txid.
3. Do commit/rollback
this would trigger alpha to determine whether executing confirm or
cancel
