Bug description:

   * MOTD does not go into details about upgradable packages being security 
fixes or just normal updates.
   * Users should be made aware if some of the security updates could not have 
been applied.
   * The fix is adding a snipped to MOTD where the number of packages kept back 
by unattended-upgrades is shown.

  [Test Case]

   * The debian/tests/upgrade-all-security is extended to check if the number 
of kept back packages are shown in MOTD and a new test is added 
(test/ to check if the list of kept back packages are saved 
   * To test the fix manually:
     1. Mark a package upgradable from the -security pocket as held, then run 
     2. Observe MOTD messate showing the number of packages being kept back.

  [Regression Potential]

   * Unattended-upgrades may crash when saving kept packages and always
  return with failure. MOTD may hang or print error while printing the
  packages kept back by u-u.

   * It is not a regression, but the log referenced in MOTD does not
  always contain explanation why each package was kept back, unless
  debugging is enabled. One case where packages are not mentioned in the
  log is when the packages are held using 'apt-mark hold' command.

  [Original Bug Text]

  Currently we have the following pieces as part of the default UX on
  Ubuntu 18.04 and later:

   1) unattended-upgrades automatically installs security updates daily by 
   2) the motd reports the number of available updates, including security 

  A user who knows about 1) also knows that a non-zero number of pending
  security updates listed in 2) is nothing to worry about.

  However, unattended-upgrades will also cleverly detect when a security
  update cannot safely be installed non-interactively due to conffile
  changes on the system.

  In this case, unattended-upgrades should also inform the user via the
  motd that these updates are not being installed.  Otherwise, there's
  nothing to tell the user that the non-zero count of available security
  updates in motd is a *problem*.

  Suggested wording:

   N security updates will not be automatically installed due to local changes.
   See /var/log/foo for details.
