This commit allows the user to change the "AllowOverride" and "Options"
directives of the documentroot directory for different vhosts.
The default values are "AllowOverride All" and "Options -Indexes
+FollowSymLinks" (see defaults/main.yml), so this commit is fully
backwards compatible.
The only real difference between apache version 2.2 and 2.4 are the
"Order/Allow" directives which have been replaced with "Require", so
there seems to be no need to maintain two separate templates.
As a side-effect, this merges geerlingguy/ansible-role-apache#69 into
the apache 2.2 config.
By default I leave it as "*", but for many cases, we don't want to bind our
apache to all network addresses available for the server. For example if we
want to only bind the apache to the localhost, we can use the following
configuration:
apache_listen_ip: "127.0.0.1"
