Description

Describe the feature

Allow passing a IAM Role to ScheduledFargateTask which in turn is passed as the role argument to EcsTask.

Use Case

The default IAM role created in EcsTask gets a policy for ecs:RunTask with the full task definition arn as the resource, that is with its revision. I want to be able to set a ecs:RunTask policy with a wild card as the task definition revision component, i.e instead of:

PolicyStatement(
    actions=["ecs:RunTask"],
    resource=["arn:aws:ecs:XX:XX:task-definition/some-task-definition:42"],
    ...
)

I want:

PolicyStatement(
    actions=["ecs:RunTask"],
    resource=["arn:aws:ecs:XX:XX:task-definition/some-task-definition:*"],
    ...
)

See: https://github.com/aws/aws-cdk/blob/66d1ed36b1628c116d5f1b3397688308d888c9de/packages/%40aws-cdk/aws-events-targets/lib/ecs-task.ts#L198-L204

Proposed Solution

My proposal is to leverage the already existing role argument on EcsTask by simply adding the same argument to ScheduledFargateTask and passing it on through.
