Description of problem:
RHEL engineering introduced default 1GB limit for LimitRequestBody starting with RHEL 9.1 https://access.redhat.com/articles/6975397. This change broken upload process for huge images via Horizon: upload fails with "413 Request Entity Too Large" error.

It is possible to use definitions like [1] to work around this problem, but for some reason it introduces 15-horizon_vhost.conf instead of 10-horizon_vhost.conf and breaks healthchecks https://bugzilla.redhat.com/show_bug.cgi?id=2252718#c1.

As a result, we need a solid fix here because more customers are migrating to RHOSP 17.1 and many of them are actually using Horizon to upload images.
