Allow iframe for trusted domains

[RuudschMaHinda]

I have a request:
I know that X-Frame-Options is like it is for a reason. Is it possible though, to maybe have a value in the config.php that can specify trusted domains to allow embedding my installation as an iframe?

I have two people who asked me if they can just embed an installation I am adminning for them for their users to have easy access from their own webpage without needing to "remember" another url to use their cloud solution. As of now they just have it open in another tab, which is fine by me. But one of them keeps coming back to me about this.

GitMate.io thinks possibly related issues are #5085 (Theming background image fails for other trusted domains), #7383 (theme changes (logo, background) only applied to first trusted domain), #9607 ([FEATURE] Allow config.php per domain name), #9541 (Nextcloud 13 - since upgrade from NC12, there are a lot of "Trusted domain errors"), and #8899 (about trusted domain running on ports not 443 and 80.).

cc @nextcloud/server-triage is this feasible?
