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.
