message_field.Detail.EXCEPTION_DETAIL_MAPPINGS contains non-exception

[Brian Rosmaita]

Seen in at least Stein and master (Train):

cinder.message_field.Detail.EXCEPTION_DETAIL_MAPPINGS dict contains this key/value pair:
UNMANAGE_ENC_NOT_SUPPORTED: ['UnmanageEncVolNotSupported']

There is no UnmanageEncVolNotSupported exception defined in the cinder.exception module.

In the current code this isn't causing a problem because that string will never match any __name__ of the __class__ of an exception, but it would probably be best to remove it. There's not an obvious exception defined in cinder.exception that matches the situation described by the detail message it maps to, namely, "Unmanaging encrypted volumes is not supported."

    Remove non-exception from EXCEPTION_DETAIL_MAPPINGS

    Removes a non-exception from the map and adds tests to check the
    consistency of message_field.Action and .Detail fields.

    Updates test-requirements and lower-constraints to use the most
    recent version of ddt allowed by current upper-constraints. (An
    included test uses the idata decorator, which allows passing an
    iterator to the test data.)
