Title:
  Nova set-password error for Ubuntu VMs

Status in OpenStack Compute (nova):
  Expired

Bug description:
  Description
  ===========
  Hi folks, i ran into a problem in OpenStack Ussuri release:
  When i was trying to use `set-password` subcommand of nova CLI to reset
  root password for my VM, it throw error (mentioned below in Actual result section). This happens on Ubuntu/Cirros VMs whereas Centos works fine.

  I searched launchpad for similar issues, but got nothing particularly for Ubuntu. I believe this
  problem may also exist in latest OpenStack distro.

  Steps to reproduce
  ==================
  * Upload any image(without QGA inside), e.g: Ubuntu18/20
  * Update the image with property: hw_qemu_guest_agent=yes
    $ glance image-update --property hw_qemu_guest_agent=yes <UUID of Ubuntu>
  * Boot new instance (e.g: QGA) with image Ubuntu and ensure instance is active/running.
  * Use cli `nova set-password <UUID of QGA>` to reset password for the instance.

  Expected result
  ===============
  state should be CONNECTED in Nova_libvirt

  e.g. virsh dumpxml <instance-number> | grep qemu.guest
  <source mode='bind' path='/var/lib/libvirt/qemu/org.qemu.guest_agent.0.instance-000000a5.sock'/>
        <target type='virtio' name='org.qemu.guest_agent.0' state='connected'/>

  Actual result
  =============
  root@server01:~/openstack# nova set-password ubuntu
  New password:
  Again:
  ERROR (HTTPNotImplemented): Unable to set password on instance (HTTP 501) (Request-ID: req-52278c9a-4cde-45d7-95cf-a87282a0b909)

  In nova_libvirt, state is disconnected
  e.g.
  <source mode='bind' path='/var/lib/libvirt/qemu/org.qemu.guest_agent.0.instance-000000a6.sock'/>
        <target type='virtio' name='org.qemu.guest_agent.0' state='disconnected'/>

  Environment
  ===========
  1. version: OpenStack Ussuri + Ubuntu20
  2. hypervisor: Libvirt + KVM
  4. networking Neutron with OpenVSwitch

  Logs & Configs
  ==============
  cat /etc/kolla/config/nova.conf
  [libvirt]
  inject_password=true
