Allow customize http vhost config using HttpdCustomization.CustomConfigSecret

[stuggi]

This change allows to customize the httpd vhost config using this parameter to specify a secret that contains service config data. The content of each provided snippet gets rendered as a go template and placed into /etc/httpd/conf/httpd_custom__ .
At the end of the vhost config in the default httpd template these custom configs get included using Include conf/httpd_custom_<endpoint>_*.

For information on how sections in httpd configuration get merged, check section "How the sections are merged" in https://httpd.apache.org/docs/current/sections.html#merging

All possible parameters which can be use in a template can be looked up in the -config-data secret of the service like:

$ oc get secret -n openstack cinder-config-data -o json | jq -r .data.TemplateParameters | base64 -d

or in the running pod of the service in the file:

$ cat /var/lib/config-data/default/TemplateParameters

The content is a versioned dump of the parameters of the service operator, like:
