Request for dockerobserver extension

[r0mdau]

Is your feature request related to a problem? Please describe.

The ecsobserver will discover all containers from all ECS nodes with the API. So all containers will be scraped by only 1 aws-otel-collector process.
Due to our scale, we prefer to install 1 aws-otel-collector per node in the ECS cluster that will scrape metrics only on its hosted containers.

Describe the solution you'd like

We would like to have in this aws-otel-collector the dockerobserver extension.

Describe alternatives you've considered

We are compiling the aws-otel-collector with the dockerobserver for our needs.

Additional context

We currently have a cluster with ~300 nodes, ~1600 ecs services and ~7500 containers running
We plan to launch 2 aws-otel-collector per node : one for metrics and one for traces. Why 2, because in our release process and configuration management it will be easier.

This issue is created following our discussions with @alolita .
