Implement new collector class that will give pod-container logs 

The container logs collector class got removed from the periscope repo in this PR: https://github.com/Azure/aks-periscope/pull/97 
For arc requirements, we need container logs for the azure-arc namespace as long as the collector is configurable to any namespace, we should be fine. 
Implementation details of this new collector class can be worked out in this thread or offline.
