Proposal: Remove OwnerID Filter from Dashboard List Swagger

[GeorgeMac]

See: https://github.com/influxdata/influxdb/blob/master/http/swagger.yml#L2398-L2402

Internally we do not expose that dashboards can be listed by owners.
Because of this, there is some URM interaction in the http handler for the dashboard service.
We are actively removing all URM interactions for services external to tenant.

influxdb/http/dashboard_service.go

Lines 322 to 342 in e51d1cb

	if req.ownerID != nil {
	filter := influxdb.UserResourceMappingFilter{
	UserID: *req.ownerID,
	UserType: influxdb.Owner,
	ResourceType: influxdb.DashboardsResourceType,
	}
	mappings, _, err := h.UserResourceMappingService.FindUserResourceMappings(ctx, filter)
	if err != nil {
	h.HandleHTTPError(ctx, &influxdb.Error{
	Code: influxdb.EInternal,
	Msg: "Error loading dashboard owners",
	Err: err,
	}, w)
	return
	}
	for _, mapping := range mappings {
	req.filter.IDs = append(req.filter.IDs, &mapping.ResourceID)
	}
	}

I propose we remove both these parts. Contributing further towards keeping resource organization scoped for now.
