Create dedicated "apache" base profile

This profile has multiple purposes:
- group common httpd configurations/instructions
- correct a small issue with the "status" mod

Until now, only Horizon was specifically including this mode, and as
httpd wasn't listening on localhost, it wasn't in use at all.

With this commit, all API using apache will be able to provide the httpd
server status on 127.0.0.1/server-status.
