"on install" was ambiguous because it wasn't clear if it meant "when npm
install is ran on this project" or "when this project is installed
somewhere else"

Adds an example of when `npm update` would not install the latest
version of a package because other subdependencies in your tree have
tighter restrictions.

along with extensive tests and user documentation.

The flattener worked for everything except for when you are using
`npm config set` itself.  Now it works for both.

This looks very wrong on white terminals.

npmlog still makes its `notice` logs do this but that will have to be
fixed in the npmlog repo.

This adds the `audit` config item to the usage output of `npm ci`, and
also tweaks how usage flags are shown for boolean options that do not
default to false.  Their usage is shown as the `--no-x` form of the flag
to better communicate that the flag is needed to turn that normally true
option OFF.

The description of `audit` was also updated to reflect that it runs on
many different npm commands, not just install.  Because this flag is
included in the usage of those commands it's best to let the assocation
happen there instead of trying to be comprehensive in the description
itself.

A small fix to make `install-ci-test` not try to redefine its own
usage, but to inherit from `ci` was also included.

It will be helpful to us when debugging the "exit handler never called"
bugs to know which timings were started but not ended.

Tests moved to use real npm.

 * npm mock logger writes to npm.log.record too now
 * No more extra process.exit from within the process `exit` event handle.
 * No more `exit()` function.  Logic is rolled up into the exit handler.
 * Now there is only an exit handler and an exit event listener.
   `lib/utils/perf.js` was rolled up into npm.js itself.

Unfortunately the tests were written in such a way that any further
refactoring of the exit handler was going to require also rewriting the
tests.  Fortunately NOW the tests are interacting with the exit handler
in a way that shouldn't require them to be rewritten AGAIN if we change
the internals of the exit handler.

Currently, the name: `npm-robot` is being used in nodejs changelogs as
the atttribution author name for npm-update commits. This makes it so
that entries in the changelog referring to our updates reads like:

```
upgrade npm to 7.18.1 (npm-robot) #39065
```

This change makes it so that the name used in commits is `npm team`,
this way the changelogs entry should read instead as:

```
upgrade npm to 7.18.1 (npm team) #39065
```
