feat: Add support for metrics collection (#1762)

<!-- please provide a detailed description of the changes made in this
pull request. -->
This PR introduces a package for instrumenting the code for metrics
collection. The new README details the environment variables that need
to be set and includes an example of how one might configure their local
pipeline to export metrics to Grafana Cloud.

I've added a few metrics in the `tm2` package; I _think_ they are in the
correct spots.

You may notice that the `metrics` subfolder in the `telemetry` package
is unnecessarily modular. This is because this package originally
include code for gathering traces as well. There is an existing issue
with this and have decide to presently exclude it from this PR until it
is fixed and/or requested -- this is a feature we would almost certainly
not want to enable in a production environment. Metrics collection is
more likely to be enabled in prod because they can be set to be exported
to a local collector application that handles more complex batching,
retry requests, and publishing to the end data store, in this case
Grafana.
