[pve-devel] [PATCH-SERIES docs/(guest-)common/qemu-server/container/manager] cpuunits improvements

[Fiona Ebner <f.ebner@proxmox.com>]

This series does multiple things, all related to cpuunits:

* Updates the documentation in pve-docs and pve-container for the
cgroup v2 cpuunits defaults and limits, while still mentioning the old
values that apply to legacy cgroup v1 hosts. qemu-server is already
updated.

* Move the get_cpuunits() helper from qemu-server to guest-common and
re-use it for containers. Makes behavior consistent with VMs and
allows starting existing containers with an out-of-range value. This
requires dependency bumps qemu-server,pve-container -> guest-common.

* Drop an unused parameter for change_cpu_shares(). Here technically,
a Breaks from common -> pve-container,qemu-server is needed, before
we can introduce a new parameter.

* Clamp cpuunits value already when setting via API.

* Broadcast the node's cgroup version as a pmxcfs kv entry. This is
the v2 of that patch, changes are noted there and use the value in
the UI to dynamically show the correct defaults and limits.
