The include path addition for metrics to the telemetry library does indeed
look like it was just missed being removed, since I can compile things up
successfully with it removed.

With regards to interaction between telemetry library and metrics library,
they are complementary but not replacements for each other. The metrics
library provides support for tracking metrics, mostly on a per-port basis.
The original telemetry library implementation was based on top of the
metrics library and supported reporting out data from that library. More
recent versions of the telemetry library have reworked that support to
allow the reporting of arbitrary telemetry data, not just from the metrics
library, but the old interface is still supported.
