Allow users with the VM.Config.HWType privilege to configure VirtIO RNG
devices on VMs with either /dev/urandom or /dev/random as the entropy
source. Users with the Mapping.Use privilege on the /mapping/hwrng ACL
path may also configure /dev/hwrng as an entropy source.
Changes since v3:
* Remove hardware RNG resource mapping and introduce /mapping/hwrng ACL
path instead
* Split some changes into separate commits
Changes since v2:
* Restrict RNG device format to enum of
* Add descriptive commit message
* Code style fixes
* Remove outdated remarks about entropy stravation of /dev/random
* Split helpers for VirtIO RNG command line arguments into its own
commit
* Add explicit "use PVE::QemuServer::RNG;" statement to PVE/API2/Qemu.pm
* Fix "map: type check ('array') failed" error when adding a mapping in
the UI
* ui: split resource mapping types into tabbed views
Changes since v1:
* Restrict use of /dev/hwrng to the root user
* introduce hardware RNG mapping
