Premise

Sample playbooks contain lot of variables that were deprecated and we should not be advertising them.

Changes

• Remove non-default modes of sap_swpm and add dedicated playbooks for execution scenarios that will be properly defined in upcoming sap_swpm PR.
• Create clear separation between roles to show how roles can be run independently.
• Update README and create clear point towards ansible.playbooks_for_sap as source for end to end playbooks, not here.

NOTE for sap_hana_preconfigure_exec.yml

The playbook sap_hana_preconfigure_exec.yml was removed without any replacement, because its implementation had following issues:

• Example with ansible.builtin.import_playbook does not work on 2.18 - 2.21 versions
• Actual purpose is limited as it expects no changes in this file (since it runs from collection home), yet it needs vars to be defined.
  @berndfinger I think having good samples has more value, but maybe you can say if you added it for some specific reason. Then I can re-add it, but only if it is working properly.
