    nova-manage doesn't validate key to update the quota

    nova-manage doesn't validate the key value supplied to
    update the quota, as a result unnecessary records will be
    created in db and user will be under the impression that
    quota value got updated.
    This patch validates the input value given to the key.

    fixes bug 1064359
