Bug Description

The lp bug 1863232 introduces a new config WSGISocketRotation that allow to disable the wsgi socket rotation for apache's mod-wsgi, and this option is disabled in apache by default so the default behavior remains consistent with the previous versions. But for charm, there is no config to set whether WSGISocketRotation is turned on or off. Moreover, sometimes allowing customers to disable rotation can solve HTTP 503 issue mentioned in the lp bug 1863232

But this HTTP 503 issue is quite difficult to reproduce, I have made the following effort, but I still cannot reproduce them so far. I also asked the customer to run the following effort on his production env, it also failed to reproduce the problem.

#eg: on nova-cloud-controller/0, run:
cat <<EOF >http-request
GET / HTTP/1.1
Host: 127.0.0.1
Connection: keep-alive

EOF
for i in {1..1000}; do echo $i; date; (cat http-request; sleep 1; cat http-request; sleep 9) | telnet 127.0.0.1 8754 2>&1 | while read line; do echo "$(date +'%T') == $line"; done >>output.txt; done

We did see HTTP 503 issue in the customer's production env, I cannot request the customer to directly modify WSGISocketRotation=Off in his production env to confirm this can fix the problem. However, I believe that since apache has provided a config to disable rotation, charm should also provide a config to allow customers to disable rotation. So, I propose adding the following config to all charms that include apache wsgi.

1, when disable-wsgi-rotaion=True, set 'WSGISocketRotation Off' in apache2

2, when disable-wsgi-rotaion=False, set 'WSGISocketRotation on' in apache2

The config disable-wsgi-rotaion will be set to False in charm side by default as well, this can avoid all potential regressions. Additionally, this config needs to be introduced to all charms that include apache wsgi, such as: horizon, keystone, glance, nova-cloud-controller, neutron-server, cinder etc

Support disabling apache wsgi socket rotation

    Bug LP 1863232 introduced a new Apache configuration option called
    WSGISocketRotation which allows users to disable wsgi socket
    rotation. This patch makes this configurable with a new
    wsgi-socket-rotation config option that defaults to the Apache
    default and can optionally be set to False.
