Description of problem:
TLS-E enabled OpenStack deployments with STF are failing due to insufficient permissions for the user 'qdrouterd' in the container 'metrics_qdr' to read OpenStack's SSL certificates. Although this does not fail the deployment, This blocks OpenStack from sending metrics to STF.

Error log from "metrics_qdr" container:
2023-03-16 03:49:47.570217 +0000 SERVER (error) SSL CA configuration failed for connection [C1] to default-interconnect-5671-service-telemetry.apps.vlan617307.rdu2.scalelab.redhat.com:443

Workaround:
Temporarily using ansible-playbook we are adjusting permissions on the required certificate files on all overcloud nodes inorder for "metrics_qdr" to send metrics to STF.

- name: fix STF
  hosts: overcloud_nodes
  gather_facts: false
  become: true
  tasks:
    - name: adjust permissions for /etc/pki/tls/certs/CA_sslProfile.pem inside metrics_qdr
      shell: |
        podman exec -it -u root metrics_qdr chmod 777 /etc/pki/tls/certs/CA_sslProfile.pem
      ignore_errors: true

    - name: run qrouterd
      shell: |
        podman exec -it metrics_qdr /usr/sbin/qdrouterd -c /etc/qpid-dispatch/qdrouterd.conf -d
      ignore_errors: true


How reproducible:
100%

Steps to reproduce:
1) Deploy Openstack(TLS-E) with STF.

Actual results:
openstack fails to send metrics to STF

Expected results:
Successful overcloud deployment with STF properly configured.
