metropolis: implement Metrics Service

This is the first pass at a Metrics Service. It currently consists of an
HTTP reverse proxy which authenticates incoming connections using the
Cluster CA and certificates, and passes these connections over to a
locally running node_exporter.

In the future more exporters will be added, and we will likely also run
our own exporter for Metropolis-specific metrics.
