This for now uses the jsNonce. That way we can easily backport it.
For 17 I will fix it properly.

This can be used by pages that do not have the full Nextcloud UI.
So notifications etc do not load there.

Fixes#13662
This will fire of an event after a Template Response has been returned.
There is an event for the generic loading and one when logged in. So
apps can chose to load only on loged in pages.
This is a more generic approach than the files app event. As some things
we might want to load on other pages as well besides the files app.

Fixes#11035
Since the child-src directive is deprecated (we should kill it at some
point) we need to have the proper worker-src available

* Deprecate our default CSP
* Add strict CSP that is always our strictest setting
* Add strict eval CSP (disable unsafe-eval)
* Add strict inline CSP (disables inline styles)
This is just to move forward and have a incremental improvement of our
CSP

This avoids having to do it at all the places we want cached responses.
We can't inject the ITimeFactor without breaking public API.
However we can perfectly overwrite the service (resulting in the same
testable effect).

This makes the new `@BruteForceProtection` annotation more clever and moves the relevant code into it's own middleware.
Basically you can now set `@BruteForceProtection(action=$key)` as annotation and that will make the controller bruteforce protected. However, the difference to before is that you need to call `$responmse->throttle()` to increase the counter. Before the counter was increased every time which leads to all kind of unexpected problems.

CSP nonces are a feature available with CSP v2. Basically instead of saying "JS resources from the same domain are ok to be served" we now say "Ressources from everywhere are allowed as long as they add a `nonce` attribute to the script tag with the right nonce.
At the moment the nonce is basically just a `<?php p(base64_encode($_['requesttoken'])) ?>`, we have to decode the requesttoken since `:` is not an allowed value in the nonce. So if somebody does on their own include JS files (instead of using the `addScript` public API, they now must also include that attribute.)
IE does currently not implement CSP v2, thus there is a whitelist included that delivers the new CSP v2 policy to newer browsers. Check http://caniuse.com/#feat=contentsecuritypolicy2 for the current browser support list. An alternative approach would be to just add `'unsafe-inline'` as well as `'unsafe-inline'` is ignored by CSPv2 when a nonce is set. But this would make this security feature unusable at all in IE. Not worth it at the moment IMO.
Implementing this offers the following advantages:
1. **Security:** As we host resources from the same domain by design we don't have to worry about 'self' anymore being in the whitelist
2. **Performance:** We can move oc.js again to inline JS. This makes the loading way quicker as we don't have to load on every load of a new web page a blocking dynamically non-cached JavaScript file.
