[NetApp] Fixed scoped account replica delete
In the ONTAP 9.8 and older, there is a bug in the zapi call `snapmirror-release-iter` when using the scoped account configuration. The operation is returning success, but the release is not occurring. To avoid this issue, the Netapp driver was changed to release with the `snapmirror-release` zapi call, instead of the one that has a bug. This new zapi call requires the field `relationship-id` to be specified and it is being retrieved from ONTAP before calling it. A small fix, not related to the bug, was made in the zapi call to `snapmirror-release-iter` because the `relationship-info-only` field was in the wrong place according to the documentation. Closes-Bug: #1934889 Change-Id: I21633d4ffe14983365b0b6239216ed5d0bbfaace (cherry picked from commita745e9c7c4
) (cherry picked from commit24545ad917
