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).

* Allow to tune the scrape tolerance
In most of the classic monitoring use cases, a few milliseconds
difference can be omitted.
In Prometheus, a few millisecond difference can however make a big
difference.
Currently, Prometheus will ignore up to 2 ms difference in the
alignments.
It turns out that for users who can afford a 10ms difference, there is a
lot of resources and disk space to win, as shown in this graph, which
shows the bytes / samples over a production Prometheus server. You can
clearly see the switch from 2ms to 10ms tolerance.
This pull request enables the adjustment of the scrape timestamp
alignment tolerance.

* Decrement active_appenders metric when no samples added
Also add a test that the metric is incremented and decremented as
expected with and without samples.

This saves memory, effort and locking.
Since every symbol is also added to postings, `Symbols()` can be
implemented there instead. This now has to build a map for
deduplication, but `Symbols()` is only called for compaction, and `gc()`
used to rebuild the symbols map after every compaction so not an
additional cost.

The compaction analysis which runs under promtool tsdb analyze can be an
intensive process which slows down the entire command.
This commit adds an --extended flag to tsdb analyze which can be toggled
for running long running tasks, such as compaction analysis.
