openstack deployments with octavia leave orphan amphora images in /tmp/ansible.* directories

Environment

• Red Hat OpenStack Platform (RHOSP) 17.1
• Red Hat OpenStack Platform (RHOSP) 16.2

Issue

• For an Octavia deployment, every time ansible workflow is being triggered, it is dumping "octavia-amphora.img" image in /tmp/ansible.* directory.
• These temporary images are not getting auto cleaned by the workflow itself and may cause space utilization issue for related filesystems.

Resolution

• Manually delete temporary ansible directories after openstack overcloud deploy finishes:

    [stack@director.example.lab ~]$ sudo find /tmp/ -name octavia-amphora.img -ls
    319727535 2169272 -rw-r--r--   1  root     root     3221225472 Oct 21 11:26 /tmp/ansible.8psgzlfw/octavia-amphora.img
      9442461 2169272 -rw-r--r--   1  root     root     3221225472 Oct 22 13:20 /tmp/ansible.05xdldxv/octavia-amphora.img
    [stack@director.example.lab ~]$ 
    [stack@director.example.lab ~]$ sudo find /tmp/ -name octavia-amphora.img -delete
    [stack@director.example.lab ~]$
