Do not pass version to the init() function #108
Description
Some users are modifying /etc/nginx/conf.d/crowdsec_nginx.conf (or the openresty one), which can break during upgrades, as the file is currently not considered as a config file.
This file is updated for each release, as the version (and type) of the bouncer is set in it.
We should probably have the bouncers install a specific version.lua that would have the type/version in it. The lua lib would import this file to get that information (with a conditional import to make sure nothing breaks if it cannot be imported for any reason).
