Describe the feature

https://aws.amazon.com/blogs/aws/announcing-amazon-ecs-managed-instances-for-containerized-applications/
https://docs.aws.amazon.com/AmazonECS/latest/developerguide/ManagedInstances.html

Use Case

I want to choose ec2 instance types but not be in charge of patching my instances.

Proposed Solution

New constructs:

• ManagedInstancesCapacityProvider (note that this does not use CapacityProviderAssociations, instead referring directly to the cluster it's associated with by name)
• ManagedInstancesService
• ManagedInstancesTaskDefinition, though the general TaskDefinition, which is directly instantiable, should be updated to work as well.

Considerations I'm aware of compared to Fargate:

• No AssignPublicIp support.

Considerations I'm aware of compared to EC2:

• No PlacementStrategies support.
• RuntimePlatform may be required to get TaskDefinitions to work on ARM.

I'm sure there are many more.
