Proposed commit message
This PR is to change GetListMetricsOutput function (which calls the ListMetrics API) to use namespaces when namespaces are given in AWS CloudWatch configuration in Metricbeat.
Instead of returning all possible metrics from CloudWatch from ALL namespaces and filter later, we only need to query the ListMetrics API to get the metrics under the namespaces that we care about.
