* Updated launch_template example to include spot and mixed ASG with worker_groups_launch_template variable

* Removed old config

* Removed workers_launch_template_mixed.tf file, added support for mixed/spot in workers_launch_template variable

* Updated examples/spot_instances/main.tf with Mixed Spot and ondemand instances

* Removed launch_template_mixed from relevant files
