[Console] Populate services.yaml in CDK for ECS RFS backfill

[mikaylathompson]

Note

This is based off of #728, so the diff is much smaller than it appears here -- it should just be the final 3 commits. It should not be merged until that one is. At that point, I'll merge from main if necessary and ensure that the diff shrinks to just the incremental commits.

Description

Backfill is added a full concept in #728, which also defines the structure for the backfill entry in the services.yaml file.

In this PR, that structure is filled out for the case of RFS running on ECS and deployed via CDK.

I also realized that cluster_name needs to be a required field because it will be necessary for the ecs update-service calls made by the RFS-on-ECS backend adapter.

Its strange that this logic is in ServicesYaml. By using polymorphism the different types can self-describe how they are formatted as json internally
