Bug Description

Steps to reproduce db purge issue

1. Create volume type.
$ cinder type-create lvmdriver-2 --is-public False
2. Associate to project
$ cinder type-access-add --volume-type f564e0ba-d9be-40fa-b28d-ff2c491bb8dd --project-id 4d9f1417e6474546b80f1ebbe7415c60

3. Delete volume type
$ cinder type-delete f564e0ba-d9be-40fa-b28d-ff2c491bb8dd
4. Run ”cinder-manage db purge 1” where 1 is the age in days of deleted volume type
5. If age in days of deleted volume type is greater than 1 above command will raise following error

    Fix db purge for volume_types FK constraint

    and volume_type_projects deleted rows.
    Delete volume_type_projects records before deleting volume_types
    to solve this issue.
