Subject: [PATCH 1/2] SECRETS: Search by the right type when checking
containers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
We've been searching for the wrong type ("simple") in
local_db_check_containers(), which always gives us a NULL result.
Let's introduce the new LOCAL_CONTAINER_FILTER and do the search for the
right type ("container") from now on.

Subject: [PATCH 2/2] SECRETS: Don't remove a container when it has children
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Let's return and log an error in case the container to be removed has
children.
The approach taken introduced at least one new search in every delete
operation. As far as I understand searching in the BASE scope is quite
cheap and that's the reason I decided to just do the search in the
ONELEVEL scope when the requested to be deleted dn is for sure a
container.
