Adds metrics for DBAAS services (OS, MySQL), see full list of metrics in whitelist.go. Broadly includes:
OS cluster health
OS cluster stats (e.g. total documents)
OS JVM usage
OS indices requests + timing
OS HTTP API stats
MySQL Replication Lag
The OS metrics use multiple exporters for different subsystems. To handle this we drop redundant node and cluster identifiers from each section as needed (see aggregation.go). Tested locally w. sample OpenSearch metrics served via an HTTP server on 127.0.0.1:9273. As expected, OS metrics are available and redundant identifiers e.g. node_host (duplicates node_name) and cluster_name (prefer dbaas_uuid in practice) are dropped.
