Add a feature to support inclusion of namespaces for log collection

[anfranek]

Some of the clusters are updated with namespaces base on new deployments which are not needed for log collection. It would be beneficial if container-azm-ms-agentconfig ConfigMap allow to collect logs only from specific namespaces.
In this case config could look like that:

[log_collection_settings]
       [log_collection_settings.stdout]
          enabled = true
          include_namespaces = ["one", "two"]

This seems to be raised in the past, however it was closed (not investigated).
#1103

thanks for the feedback on this. We will add to our backlog and prioritize to get this.
