      operation: string, Identifies the operation addressed by this request. (required)
      clientOperationId: string, For mutating operation requests only. An optional identifier
    specified by the client. Must be unique for operation resources in the
    Operations collection.
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format

`list(project, managedZone, pageToken=None, maxResults=None, sortBy=None, x__xgafv=None)`

    Enumerate Operations for the given ManagedZone.

    Args:
      project: string, Identifies the project addressed by this request. (required)
      managedZone: string, Identifies the managed zone addressed by this request. (required)
      pageToken: string, Optional. A tag returned by a previous list request that was truncated.
    Use this parameter to continue a previous list request.
      maxResults: integer, Optional. Maximum number of results to be returned. If unspecified, the
    server will decide how many results to return.
      sortBy: string, Sorting criterion. The only supported values are START_TIME and ID.
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format
