morgan fainberg a38d4a650f Add immutable option for roles and projects
Add in support for immutable roles and projects (including domains).
If the immutable option is set for a role or a project that
resource may not:

* Be Deleted

* Be Updated, except to change the value of "immutable" from
  `True` to `False` or `None` (None explicitly unsets the
  resource option).

* For projects (and domains), project tags cannot be created,
  updated, or deleted.

The immutable check is performed at the manager layer allowing
for exceptional code-cases to work directly with the driver.
