opentelekomcloud_ecs_instance_v1 does not support ecs groups (scheduler_hints)

Support ECS Groups with opentelekomcloud_ecs_instance_v1

As described in the API Documentation ECS groups (os:scheduler_hints) can be set along with the creation of an ECS instance, but the module opentelekomcloud_ecs_instance_v1 doesn't seem to support that. However, the module opentelekomcloud_compute_instance_v2 does support it.
