prom: basic builtin prometheus stats exporter
This is a vpp builtin alternative, not a replacement, for the existing vpp_prometheus_exporter. The plugin works by registering with http_static as a url handler for stats.prom and handles requests by scraping the stats segment in the main thread. It will therefore consume vpp process cpu cycles. By default the plugin is disabled. To enable, first start the http static server an then use "prom enable" cli.
