- Modified puck.incus.yml to add Athena service and configuration details, including user, group, directory, port, and domain.
- Updated titania.incus.yml to change OAuth client ID and secret variable names for consistency with Athena.
- Added Athena configuration to mcpo config template, including URL and authorization headers.
- Updated HAProxy configuration template to reflect changes for the Taurus Production Environment, including SSL settings and rate limiting for specific endpoints.
- Introduced new playbooks for certificate distribution and validation with OCI Vault, ensuring certificates are correctly managed and renewed.
- Added hooks for uploading renewed certificates to OCI Vault and validating their integrity.
- Enhanced the HAProxy configuration playbook to ensure proper service management and verification of the HAProxy service.
