Warm dynamic page cache for authenticated users

Hi all together,

I have a ready to use Warmer Plugin which uses the mechanism from "drush user:login" with a one time token and subsequent requests with cookie-jar context implementation. It's pretty much the same as the CDN implementation, with one restriction: it accepts only paths with a fixed base URI (scheme and domain), not full URLs.

It is ready to be contributed. Let's discuss a proper name. What about these suggestions?

* warmer_backend
* warmer_login
* warmer_authenticated

Any suggestions?

Cheers,
Daniel

Another approach, which I found very interesting, is from this repository (but seems unfinished).

In short: they try to use an EventSubscriber on every request for checking a unique token from a cookie value and the account_switcher to get the user session.

The warmer itself is just requesting urls with the token in that cookie.

Advantage: one does not need a "preflight" login request for every user.

Disadvantage: security concerns since it is kind of an alternative session handling (for every request). Any performance impacts? Cannot tell...

Can we warm (cache) ajax requests?
For example webform dialog?
