AppFwk: Generic apps fail to apply with no clear error

[Igor Pires Soares]

Brief Description
The hello-kitty app is a custom app used in testing to validate custom containers, even after adding the necessary 'supported_k8s_version' field in the metadata file, the app is uploaded but it instantly fails to apply, checking the sysinv.log file only shows that the operation is aborted.

Severity

Minor: System/Feature is usable with minor issue

Steps to Reproduce

get hello-kitty-new.tgz file
upload app tgz
apply hello-kitty app

Expected Behavior

app is applied successfully

Actual Behavior

App fails to apply.

    Fix support for generic StarlingX apps

    This commit fixes the support for StarlingX applications that do not
    provide any plugins, also known as generic apps. Two changes were
    required to fix that regression:

      * Check if the app is generic when retrieving its charts. A previous
        commit [1] introduced a check to verify whether charts are enabled,
        which caused false negatives because generic apps do not provide
        plugins to tell if they are enabled or disabled. In light of that,
        all charts provided by generic apps should be considered as enabled.
      * Swap the order that the "_get_list_of_charts" and
        "generate_helm_application_overrides" methods are called during the
        application apply process. The call to
        "generate_helm_application_overrides" requires application charts to
        be passed as a parameter, so "_get_list_of_charts" should be called
        first.

    In addition, an error log message was added to cover the scenario where
    no application charts are found. That will provide better information
    for developers that eventually makes mistakes when structuring their
    apps. Otherwise, the apply process would silently abort with no clear
    error.

    Test Plan:
    PASS: build-pkgs -a && build-image.
    PASS: AIO-SX fresh install.
    PASS: Upload/apply/remove/delete generic app.
    PASS: Upload dell-storage app.
          Enable csm-replication replication chart.
          Apply user overrides.
          Apply dell-storage.
          Confirm that the enabled chart was installed.
          Remove/Delete dell-storage.
