Fixes #1092 - Adds CheckForReboot in packages update scenario

[sayan3296]

Attempting to fix #1092

When executing "foreman-maintain packages update", it does everything else fine, but it never shows whether a system reboot would be needed or not, and that is something important.

With Procedures::Packages::CheckForReboot included in that action, this now correctly shows whether a reboot is required or not.

Example:

When not needed:

--------------------------------------------------------------------------------
Unlock packages:                                                      [OK]
--------------------------------------------------------------------------------
Update package(s) :                                                   [OK]
--------------------------------------------------------------------------------
Running satellite-installer :                                         [OK]
--------------------------------------------------------------------------------
Check if system needs reboot:                                         [OK]
Updating Subscription Management repositories.
No core libraries or services have been updated since boot-up.
Reboot should not be necessary.
--------------------------------------------------------------------------------
Check status of version locking of packages: 
  Automatic locking of package versions is enabled in installer.
  Packages are locked.                                                [OK]
--------------------------------------------------------------------------------

And when needed:

--------------------------------------------------------------------------------
Unlock packages:                                                      [OK]
--------------------------------------------------------------------------------
Update package(s) :                                                   [OK]
--------------------------------------------------------------------------------
Running foreman-installer :                                           [OK]
--------------------------------------------------------------------------------
Check if system needs reboot:                                         [WARNING]
Updating Subscription Management repositories.
Core libraries or services have been updated since boot-up:

The Redmine issues check seems to still be expecting a redmine issue and even traced an issue with id 1092 ( https://projects.theforeman.org/issues/1092 )

Should i edit that Redmine issue and remove the PR from there ( if it allows me to do ) ?
