AWS Batch adds improvements to UpdateComputeEnvironment API

AWS Batch now expands the Compute environment (CE) configuration parameters that can be updated without having to recreate compute environments. Previously customers used UpdateComputeEnvironment API to change CE state, desired CPU count, min and max vCPU count, and service role. To update additional configuration parameters, customers have to create new CEs. With this launch, customers can use the UpdateComputeEnvironment API to dynamically update CE configuration parameters such as AMI, EC2 launch templates, instance types, and more. Rather than having to manually create a new CE to use the updated configurations, Batch will use the updated CE configuration while launching new instances and terminate instances using old CE configuration once the jobs running on them are completed.
