Support atomic transactions
Summary
========
Support atomic transactions for lease.
Problem description
================
In case of a failure of lease, the environment should be reverted back to pre-lease state.
e.g. reverting lease state[3], removing corresponding aggregates.
Use Cases
---------------
- As Wei, I want to receive an appropriate error message in case the a RUR is not
successful. In case of a failure of RUR I want the environment to be reverted back to
pre-RUR state. In other words, RUR transaction should be Atomic. In case of RUR failure,
the error message should contain sufficient information such that user can take actions
to modify the RUR. (Capacity management user story [2])

Update reference [2] to https:/
From the discussion at Dublin PTG, the atomic transaction is already achieved by the state-machine BP. If there is a situation where the state-machine doesn't help atomic transaction, make the BP higher priority. https:/
Stein PTG: this should be already handled by the state machine.
