msven ae4c246a3c ec2_asg: fix #28087 and #35993 (#36679) ... Fixes #35993 - Changes to update_size in commit eb4cc31 made it so the group dict passed into update_size was not modified. As a result, the 'replace' call does not see an updated min_size like it previously did and doesn't pause to wait for any new instances to spin up. Instead, it moves straight into terminating old instances. Fix is to add batch_size to min_size when calling wait_for_new_inst. Fixes #28087 - Make replace_all_instances and replace_instances behave exactly the same by setting replace_instances = current list of instances when replace_all_instances used. Root cause of issue was that without lc_check terminate_batch will terminate all instances passed to it and after updating the asg size we were querying the asg again for the list of instances - so terminate batch saw the list including new ones just spun up. When creating new asg with replace_all_instances: yes and lc_check: false the instances that are initially created are then subsequently replaced. This change makes it so replace only occurs if the asg already existed. Add integration tests for #28087 and #35993. (cherry picked from commit a2b3120e85)		2018-03-28 17:36:32 -04:00
