Handle old to new config when normalizing the config (#5658)
* immediately take the `safelist` values into account

Currently we had to manually add them in the `setupTrackingContext`,
`setupWatchingContext` and the `cli`.

This was a bit cumbersome, because the `safelist` function (to resolve
regex patterns) was implemented on the context. This means that we had
to do something like this:

```js
let changedContent = []
let context = createContext(config, changedContent)
for (let content of context.safelist()) {
  changedContent.push(content)
}
```

This just feels wrong in general, so now it is handled internally for
you which means that we can't mess it up anymore in those 3 spots.

* drop the dot from the extension

Our transformers and extractors are implemented for `html` for example.
However the `path.extname()` returns `.html`.

This isn't an issue by default, but it could be for with custom
extractors / transformers.

* normalize the configuration

* make shared cache local per extractor

* ensure we always have an `extension`

Defaults to `html`

* splitup custom-extractors test

* update old config structure to new structure

* ensure we validate the "old" structure, and warn if invalid

* add tests with "old" config, to ensure it keeps working

* add missing `content` object

* inline unnecessary function abstraction
