    coraid: fix snapshot deletion

    Currently, a request to ESM API for a snapshot deletion looks this way:

    {'addr': 'cms',
     'data': {
        'repoName': repository_name,
        'lvName': snapshot_name},
     'op': 'orchStrLunMods',
     'args': 'delClSnap'}

    This is correct, however, some versions of the ESM API have a bug that
    prevents it from validation this valid request and it fails with:

    Must define the new LV name to be assigned to the clone/clSnap.

    As a workaround for this bug, provide an 'newLvName' property with a
    'noop' value to make the validation pass even on buggy versions.

    Fixes bug #1365417
