Preview-Experimental Support EL10 as Management Server and KVM host (#10496)

* cloudstack: add support for EL10
This adds support for Fedora 40 and (upcoming) EL10 distro to be used
as mgmt/usage server, mysql/nfs & KVM host. Python3 version has changed
to 3.12.9 which isn't automatically determining the python-path.
* python: WIP code, this fails right now
Need to discuss/check if we can skip this code. Where/how is cgroup
setup used with KVM agent.
* prep cloudutils to be EL10 ready
Fixes issue for Fedora, it was running old EL6 hooks which isn't
applicable for modern Fedora version that are closer to EL8/9/10
