Describe the issue you're reporting

So I was trying to use awsecscontainermetrics receiver and found out that it supports limited amount of metrics and there is more info available in AWS ECS container insights.
So I am thinking about a way that we can add support for ECS API within awsecscontainermetrics receiver which will contain more extended custom metrics which might be helpful for other users.
I am thinking about running a sidecar container approach.
However, let me know if any other way is possible or any guidance regarding the implementation details.
Thanks!!

Also, let me know if i can work on this ECS API integration.
