Additional prop support added for all metrics.

[musa-asad]

Description of the issue

Public docs state that the drop_original_metrics feature is supported, but, when we try to run it, the config translation states it isn't allowed: Under path : /metrics/metrics_collected/statsd | Error : Additional property drop_original_metrics is not allowed.

Description of changes

I allow drop_original_metrics for the statsd metric as well as other metrics that didn't have it (collectd and ethtool) and adjusted the CW exporter translator code to allow for this.

Tests

I first replicated the issue and then tried running CWAgent with the following config:

{
    "metrics": {
        "aggregation_dimensions": [
            ["InstanceId"]
        ],
        "metrics_collected": {
            "statsd": {
                "service_address": ":8125",
        "metrics_collection_interval": 10,
                "metrics_aggregation_interval": 50,
        "drop_original_metrics": ["should_drop_24"]
            }
        }
    }
}

The relevant errors are as follows (when we try using drop_original_metrics for all metrics collected):

Under path : /metrics/metrics_collected/ethtool | Error : Additional property drop_original_metrics is not allowed
Under path : /metrics/metrics_collected/collectd | Error : Additional property drop_original_metrics is not allowed
Under path : /metrics/metrics_collected/statsd | Error : Additional property drop_original_metrics is not allowed

After that, I re-ran the configuration and the error didn't persist.

Then, I ran echo "should_drop_24:123|c" | nc -u -w1 127.0.0.1 8125 and echo "should_not_drop_24:123|c" | nc -u -w1 127.0.0.1 8125.

As expected, the should_drop_24 didn't show up in the CW console, but should_not_drop_24 did.

We also see this in the yaml file:

exporters:
    awscloudwatch:
        drop_original_metrics:
            should_drop_24: true

Mind adding a screenshot of what the metrics look like in CW console? I would have expected an append_dimensions for the InstanceId so Im curious how it worked without that.
