* made ipset inventory metric more efficient for container insights scraping. Added metric for total ipset entries
* updated comment for GetVecValue
* changed prometheus metrics port number from 8000 to 10091 to be next to the node port used in CNS
* added cluster service for NPM Prometheus metrics (lets a scraper only scrape this service for node redundant metrics)
* separated node and cluster metrics into separate registries and HTTP endpoints
* separated functionality for getting IPSetInventory labels and made public
* updated initialization of IPSetInventory to have hash set label and changed ipsm tests to mirror this
* added two yaml options for configuring a prometheus server to scrape NPM efficiently. Removed generic prometheus annotations on NPM pod to prevent default scraping of NPM for a helm prometheus server, and added a specific annotation for the alternative prometheus server config
