At the end of the install or upgrade, do an HTTP GET /

So the user, on first use, has warm caches already.

Need this first: uboslinux/ubos-admin#517

Actually not an HTTP GET, but the equivalent from the command-line, so Apache does not need to display the app yet.

I cannot accomplish this with php index.php or thereabouts, because Nextcloud behaves very differently depending on whether OC::$CLI is true or false, and that is determined from a call to php_sapi_name() somewhere down in the call stack. It cannot be easily overridden.

The best way to solve this would be for Nextcloud to have an occ prime-caches command or something like that. Filed issue upstream: nextcloud/server#14463

Now it is blocked by uboslinux/ubos-admin#651.
