octavia api doesn't get along with haproxy

[Brent Eagles]

The octavia api currently runs under wsgiref.simple_server. Unfortunately this doesn't work well with haproxy and produces repeated stack traces, spamming the journal. The proposed solution is to move forward to running octavia under apache immediately.

    Run octavia-api under httpd

    octavia-api's cli app doesn't behave well with haproxy so let's run
    under apache and save ourselves some grief. Also adds cleanup for the
    octavia-api tls proxy in update and upgrade tasks if it was previously
    deployed.

    Also updates zuul layout for multinode job to track changes to new
    flattened octavia service files.
