Description of problem:

If I try to delete a storage connection via API-Call (no matter if via rest-client, curl, or ovirt-shell) the delete method fails.


Version-Release number of selected component (if applicable):

this occurs in ovirt 3.3

How reproducible:

always

Steps to Reproduce:
1. find a storage connection id, e.g. brows to the specific api entrypoint:
https://www.example.com/api/storageconnections 
2. try do delete this connection via curl/rest-client/ovirt-shell:
e.g.:
[oVirt shell (connected)]# remove storageconnection 84970346-ae22-49cf-8a4c-c1bd27a0b7a4

Actual results:
in ovirt-shell you get:
error:
status: 404
reason: Not Found
detail: Entity not found: null

But you can list the connection via shell, so it exists:

[oVirt shell (connected)]# show storageconnection
84970346-ae22-49cf-8a4c-c1bd27a0b7a4

id     : 84970346-ae22-49cf-8a4c-c1bd27a0b7a4
address: server1
path   : /var/lib/exports/export
type   : nfs

Via REST-Client you get: "The specified HTTP method is not allowed for the requested resource" (See the attached screenshot)

Expected results:

The Storageconnection gets deleted

Additional info:

The Storage Domain associated to this connection was an export domain, which got deleted, but the connection persisted.

As an side effect, we can no longer add additional local storage domain, in a third local storage datacenter because then it says:
"can't add storage connection, connection already exists"
