Fixes #36693 - Add new host status for RHEL lifecycle

[jeremylenz]

What are the changes introduced in this pull request?

• Add a new host status, Katello::RhelLifecycleStatus which tells you if your RHEL system is getting close to EOS (end of support).
• Hard-code a list of EOS schedules, which we'll have to update whenever they change and whenever a new major RHEL is released.
• Add methods that can be used in a future report template
• Update all relevant host statuses on host registration and checkin.
• Update all relevant host statuses on errata recalculate.

Considerations taken when implementing this change?

What are the testing steps for this pull request?

Register at least one RHEL host. It should get a RHEL lifecycle status immediately on registration.
CentOS and other OS hosts will show "N/A" for RHEL lifecycle status.

To force host status updates:

host.refresh_statuses

note: This will refresh RHEL lifecycle status only for RHEL hosts. This is expected.

View host statuses on the new host details page, or in Rails console:

host.get_status(Katello::RhelLifecycleStatus).to_label

• Verify that new host methods work

host.rhel_lifecycle_status
host.rhel_lifecycle_status_label
host.full_support_end_date
host.maintenance_support_end_date
host.extended_support_end_date
host.approaching_end_of_support_date
host.end_of_support_date

• Newly registered hosts should have their statuses updated, as well as hosts checking in (subscription-manager repos)
• Scoped search should work and auto-complete for the new statuses (rhel_lifecycle_status = full_support, etc.)
• Fake different statuses by changing def self.to_status in app/models/katello/rhel_lifecycle_status.rb
• Fake different EOS schedules by changing def rhel_eos_schedule in app/models/katello/concerns/operatingsystem_extensions.rb

Is it safe to assume all RHEL OSes use "RedHat" as the name? Or do some use "RHEL" ?

[lfu]

Seems they are all RedHat for RHEL 9, 8 and 7.

@chris1984 do you happen to know what the strings are for RHEL6 and RHEL5? 😄

[chris1984]

@jeremylenz Should be good to go with 6 too:

irb(main):004:0> Operatingsystem.second
=> #<Redhat id: 6, major: "6", name: "RedHat", minor: "10", nameindicator: nil, created_at: "2023-09-01 13:51:18.161260000 +0000", updated_at: "2023-09-01 13:51:18.161260000 +0000", release_name: nil, type: "Redhat", description: nil, password_hash: [FILTERED], title: "RedHat 6.10">

Added maintenance_warn_date so RHEL7 should now show "Approaching end of maintenance support (2024-06-30)"

[jeremylenz]

fixed tests

Added maintenance_warn_date so RHEL7 should now show "Approaching end of maintenance support (2024-06-30)"

I saw this message in green color 😃

[jeremylenz]

@lfu Made approaching maintenance a warning status (should be yellow now) and cleaned up self.to_status.

[jeremylenz]

@lfu Updated -

• removed warn_date methods
• added def self.approaching_end_of_category (sorry, I renamed it)
• added case statements
• updated tests
• refresh only errata and RHEL lifecycle status during errata applicability check (which is during host checkin)

[lfu]

Nice job 👍🏻
