I would like to avoid extra API call's to determine if we are running in
Agent Mode, so I think we could use this approach.
This is a bootstrap of #9612

* Initial draft of prometheus-agent
This commit introduces a new binary, prometheus-agent, based on the
Grafana Agent code. It runs a WAL-only version of prometheus without the
TSDB, alerting, or rule evaluations. It is intended to be used to
remote_write to Prometheus or another remote_write receiver.
By default, prometheus-agent will listen on port 9095 to not collide
with the prometheus default of 9090.
Truncation of the WAL cooperates on a best-effort case with Remote
Write. Every time the WAL is truncated, the minimum timestamp of data to
truncate is determined by the lowest sent timestamp of all samples
across all remote_write endpoints. This gives loose guarantees that data
from the WAL will not try to be removed until the maximum sample
lifetime passes or remote_write starts functionining.

This updates React, TypeScript, and some other node packages (but not
everything).
A couple of notes:
- `enzyme-adapter-react-16` does not have a React 17 equivalent yet, so I
switched to the fork `@wojtekmaj/enzyme-adapter-react-17`
- A bunch of tests are still failing because I think in the enzyme testing
environment, a browser API (`ResizeObserver`) is missing, and maybe for other
reasons. This needs to be explored + fixed.
- The TypeScript update introduced more stringent rules, which required fixing
up a bunch of pieces of code a bit.
- The `use-media` package doesn't work with React 17 yet, so I just built our
own minimal `useMedia` hook instead (just a couple of lines).
- I commented out part of the code in `withStartingIndicator.tsx` because it
fails the now-stricter lint checks. It needs to be fixed (and not commented
out).
