Send httpd vhost logs to journald via systemd-cat

[Alleny244]

Why are you introducing these changes?

foremanctl deploys httpd as a host service, but the Foreman vhosts currently write access and error logs to files under /var/log/httpd/. This does not align with the containerized logging model, where logs should be written to stdout/stderr and collected by journald.

On EL9, logging directly to /dev/stdout was unreliable under systemd. Using systemd-cat with dedicated journal tags provides reliable integration with journald.

What are the changes introduced in this pull request?

• Update foreman-vhost.conf.j2 and foreman-ssl-vhost.conf.j2 to pipe access and error logs through systemd-cat instead of writing to /var/log/httpd/.
• Add integration tests to verify:
  • vhost configuration uses systemd-cat
  • HTTPS access logs are written to the system journal

How to test this pull request

1. Deploy foremanctl from this branch.
2. Verify the generated Apache configuration uses systemd-cat:

   grep -E 'ErrorLog|CustomLog' /etc/httpd/conf.d/foreman-ssl.conf

3. Generate an HTTPS request:

   curl -sk https://localhost/api/v2/ping

4. Confirm the request appears in the journal:

   sudo journalctl -t httpd-ssl-access --since "1 min ago" --no-pager

5. Verify the old log files under /var/log/httpd/ are no longer being updated.
6. Run the new integration tests.
