Ignored linuxParameters after service update

[vtatarin]

Hi! Thank you for developing such a great tool.

However, after switching from using tini in our containers to embedded initProcessEnabled docker parameter I have discovered the following issue:

after updating any ECS service with ecs-goploy (and ecs-deploy too) linuxParameters section of task definition (which contains the needed initProcessEnabled parameter) is set to null. See example below.

before ecs-goploy:

"linuxParameters": {
        "capabilities": null,
        "sharedMemorySize": null,
        "tmpfs": null,
        "devices": null,
        "initProcessEnabled": true
      }

after updating the service:

"linuxParameters": null

Hmm... ecs-goploy does not change linuxParameters in current task definition. Probably AWS API updates the section to default value when create a new task definition.
So we have to override it with current value.
