  - Allow passing any values to override.yaml

    This change allows passing any values that will then
    be stored to override.yaml.
    These values are passed from the "overrides" key, that
    may be set either as an extra variable or in inventory/group_vars.
    The root certificate is merged with the overrides dictionary before
    saving the file.

  - Improve application role testability

    Remove different phases for application role as
    those are supposed to run after each other anyway
    from playbook and pre/post steps can be disabled
    by other means.

    Enable Helm override file generation customization by
    delegating it to separate role.

    Separate Helm file transfer to own module.

    NOTE: install.yml with all Helm commands (shell/command)
    is not idempotent and should be fixed with separate
    commit.
