Title:
  [SRU] Backport v7.20.2 of xe-guest-utilites from Lunar to Jammy

Status in xe-guest-utilities package in Ubuntu:
  New
Status in xe-guest-utilities source package in Jammy:
  Fix Committed
Status in xe-guest-utilities source package in Kinetic:
  Fix Committed

Bug description:
  [ Impact ]

  Some xen-based public clouds utilize the xe-guest-utilities package to
  perform hyper-visor based communications for boot-time discovery
  hostname, network configuration, etc. One of our cloud partners
  requested the inclusion and availability to see v7.20.2 in the Jammy+
  archive.

  [ Test Plan ]

  Since this needs a particular setup, CPC shall spun up an validation
  image and run the initial set of tests and then send it across to our
  customer to do the final test. Upon successful internal and external
  validation, we'll paste the results of the same and thereby complete
  the verification.

  [ Where problems could occur ]

  Since we're introducing a new package (src:xe-guest-utilities was
  removed Focal onward and now we're re-introducing it), the chances of
  regression is almost nil. But perhaps a race condition with some other
  package could introduce problems but this should be caught whilst
  building the image.
