Aodh-api keep restarting caused by port conflict.

[Eddie Yen]

In Ubuntu binary container. The aodh-api keep restarting after deployment.
Check its docker logs and found below errors:

AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 10.111.82.2. Set the 'ServerName' directive globally to suppress this message
(98)Address already in use: AH00072: make_sock: could not bind to address [::]:8042
(98)Address already in use: AH00072: make_sock: could not bind to address 0.0.0.0:8042
no listening sockets available, shutting down

This issue is similar to https://bugs.launchpad.net/kolla/+bug/1832306 which the comment notified.

Checked the container and found:

/etc/apache2/sites-enabled/aodh-api.conf
/etc/apache2/sites-available/aodh-api.conf

existed inside the aodh-api container.

We may need to delete these config file either when building the images on Ubuntu binary.

    Delete default gnocchi & aodh wsgi conf in Ubuntu binary

    Ubuntu distro package will create default wsgi conf in apache
    during gnocchi-api and aodh-api installation. We need to delete
    them since we only use the conf that pushed by kolla-ansible.
