Open Stack

Hello everyone,

Keystone started emitting notifications [1] for users and tenants being created / updated /
deleted during the Havana cycle. This was in response to bug [2], the fact that OpenStack
doesn't clean up after itself when tenants are deleted. Currently, Keystone does not emit
these notifications by default, and I propose it should. According to the principle of least
surprise, I would imagine that if an admin deleted a tenant he would expect that all of its
resources would be deleted, making the default configuration values in Keystone and the other
projects very important. I wouldn't want to rely on the different deployment tools to change
the needed configuration values.

I was hoping to get some feedback from operators regarding this.
