[ECS] Add support --oom-kill-disable docker arg

### Summary

ECS should support the `--oom-kill-disable` docker flag

### Description

We have an application that uses up as much memory as it can as performance is proportional to memory, so we set a hard limit on the containers in ecs, however the OOM killer kills the application as soon as the application receives an OOM, even though the application is equipped to handle OOM errors appropriately. Is there anyway we can disable the OOM killer for ECS containers which resembles the `--oom-kill-disable` flag in docker or can we add this feature?

The issue names ECS containers and Docker's `--oom-kill-disable` flag but provides no repository files, tests, or implementation entry point. Start by determining whether ECS exposes an equivalent container setting and what service constraints apply. Done would mean a supported way to disable the OOM killer for ECS containers, with the behavior documented and verified.
