YDB Ansible playbooks v0.2
This is the second pre-release of YDB Ansible playbooks, with the following modifications:
- support configuration files backup on configuration updates;
- switched to Ansible 'become' instead of direct 'sudo' usage;
- more correct 9-node configuration file sample shipped;
- added extra checks to ensure that database creation actually worked;
Future releases will focus on re-usability aspects, and will deliver the playbooks in the form of Ansible Collection.
