NBI

Description

In Feature 7270, NBI API is capable of getting list of NFVI metrics which OSM supports. But those APIs can only fetch one grain of a metric from Prometheus at the time of request. It can be improvised to collect historical data for the user specified timestamp durations i.e,'from:&end:'

Demo or definition of done

Working API which will fetch collection of metrics for the user specified time intervals.
