  - Merge "haproxy: skip redundant backend configuration for memcached"
  - haproxy: skip redundant backend configuration for memcached

    Previously, Kolla-Ansible generated unnecessary HAProxy backend
    configuration entries for the memcached service. These backend entries
    were redundant since memcached is not accessed through HAProxy by any
    OpenStack service. This patch removes the redundant configuration,
    keeping the HAProxy configuration minimal and consistent with actual
    service usage.
