Make Jetty http.threadpool options available in config

[runarmyklebust]

Seems like we just use default properties for jetty in xp, without any possibility to tune threadpool-settings.

We have seen issues in production where the default max number of jetty-threads (200) with a long timeout (60s) makes the server unresponsive.

@GlennRicaud this one should be fixed asap

Remember to update the docs!

@rymsha You have additional information I do not have or that was not already discussed the other day?

[GlennRicaud]

Remember to update the docs!

@sigdestad Could you remember to finish the documentation when you have the time. We cannot update the doc when it is still in progress

[rymsha]

I noticed this issue created some time ago reflects exactly what we have discussed another day, yes.

Thus the update above "
@GlennRicaud GlennRicaud changed the pipeline from Ready to Current Sprint for Agile 5 days ago" ;)
No need for you to worry about the prioritization of tasks

The doc is open for anyone to edit, it is in git
