For some reason, only NotImplementedError in _error_out_instance_on_exception would use the $instance_state parameter which can be controlled by the caller of the context manager to determine the rollback vm_state. But in the case of InstanceFaultRollback, the caller may want to reset the vm_state back to something other than ACTIVE, like if the instance is actually STOPPED and something like prep_resize fails (you can resize a STOPPED instance). This change makes _error_out_instance_on_exception handle InstanceFaultRollback like NotImplementedError in that the instance_state parameter is used to reset the instance.vm_state. It also adds a docstring explaining how this context manager works along with some notes/questions about ways to improve it. Change-Id: Ie4f9177f4d54cbc7dbcf58bd107fd5f24c60d8bb Related-Bug: #1811235

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:
