Because it's more than just pure configuration, but a fpm pool
definition, I've changed the following variables in Ansible :
- php_fpm_defaults_conf_file to replaced by php_fpm_default_pool_file
- php_fpm_custom_conf_file to php_fpm_default_pool_custom_file.
On the FPM side, I've also changed the files names of the pool to make
them more explicit. No more z and zzz. It's the www pool, so let's put
www in the file name for coherence :
- z-evolinux-defaults.conf changes to www-evolinux-defaults.conf
- zzz-evolinux-custom.conf changes to www-evolinux-zcustom.conf
