all: Complete overhaul with new Interactive Mode, variable fragments, publishing automation and updated playbooks

[marcelmamula]

Description

This pull request is major overhaul of whole repository in order to create base for simpler updates using publishing automation.
All changes originate from original proof of concept #45.

Changes

all: Add fragments with Interactive prompts, platform images and vars #57

• New Interactive Mode supporting all non-experimental platforms and scenarios. Full documentation is present at common_fragments/tasks/interactive/README.md
• New folder common_fragments that will be used for re-used variables and tasks, shared across all scenarios.
• New platform variable fragments for separate management of OS images and Platform variables.

Add github action for publishing stage to main #58

• New github action automation that will be used for distributing common_fragments across scenarios.

all: Update all scenarios with new fragments and new workflow #59

• All scenario extravars are split into fragments
  • _base that contains scenario specific variables
  • _spec that contains host specification
• Playbook is updated to:
  • Include new interactive mode from all: Add fragments with Interactive prompts, platform images and vars #57
  • Simplify var lookup to reduce long lines and reuse them
  • Move some functionality from sap_vm_provision to playbook to reduce dependencies and enable existing_hosts
• Replaced hana and swpm dictionaries (sap_swpm_templates_install_dictionary) with one common for both sap_software_install_dictionary in order to simplify playbooks
  • Move wildcards into sap_software_install_dictionary
  • Move distributed system entries one level lower so we can make lookup easier - all will be under product, not product+group
• Added comments to all variables in extravars files

Test Results

All scenarios were tested on SLES 15 SP6 on AWS with exception of sap_ecc_ibmdb2_distributed_ha which needs some work as documented in #60

All scenarios were tested along with recent improvements that are not released yet!

• sap_anydb_install_oracle: Add handling of OS specific vars community.sap_install#1033
