v3.8.0: Release 3.8.0

New Features

• Percona backup operations now use a default backup image, eliminating
  the need to specify an image for each individual backup job. This
  streamlines the backup configuration process and reduces configuration
  overhead for operators managing database backups.
  The default image is automatically applied to all backup jobs unless
  explicitly overridden, ensuring consistent backup tooling across the
  cluster while maintaining flexibility for advanced use cases.

Bug Fixes

• Add openstack_resource_controller in the atmosphere_images variable this
  way the image_manifest also is able to pickup this image to mirror the
  image to a local registry.

• Fixed Helm release upgrade failures for Jobs by adding Helm hook annotations.

Other Notes

• Add the OctaviaLoadBalancerMultipleMaster alert to detect when an Octavia load balancer has
  multiple MASTER Amphorae for more than 15 minutes. Having multiple masters may cause frequent port
  revision and rebinding across different hosts, resulting in performance degradation.

• Updated Ceph monitoring with new dashboards for Non-Volatile Memory Express
  (NVMe) over Fabrics, multi-cluster overview, Server Message Block (SMB),
  and application overview, along with improved alerts and metrics.

• Updated node exporter monitoring with improved alerts and dashboards for
  system monitoring.

• Updated CoreDNS monitoring with refined alerts for DNS query performance
  and forwarding issues.

• Fixed alert manager configuration for alert routing.
