feat(bootstrap): an openEuler 24.03 LTS host is set up as a compute

The compute bootstrap found openEuler but had no install function for
it, so it stopped. Now it installs qemu, libvirt, python3-libguestfs
and cyrus-sasl (openEuler's names; it has no EPEL), applies the RHEL
family's qemu.conf, SASL and gstfsd steps, and runs the monolithic
libvirtd with its TCP socket: openEuler 24.03 ships modular daemons
only for qemu and the proxy.

Tested in an openEuler 24.03 container with /dev/kvm: the full live
suite over TCP (SASL) ran 2145 tests. What failed is libvirt 9.10's
(reverting a running VM's external snapshot, live clone needs 11.10),
the test host's (no pool named default), and its SeaBIOS, which
prints no banner on the serial port.

 2. For SSH connections, give the user the panel runs as an SSH key and copy it to the compute node. **Use only the block for your installation type:** a key set up with the host commands is not seen by the panel in Docker. `ssh-copy-id` asks for the compute node's root password once. `accept-new` accepts a new host's key on first connect and refuses a changed one.
