Added crowdsec openresty bouncer support

[LePresidente]

This adds support for Nginx Proxy Manager to be a firewall bouncer for Crowdsec

Blog post on what this does
https://crowdsec.net/blog/nginx-bouncer-v1/

This has been expanded to be a permanent addon to Nginx Proxy Manager,
This requires the following changes to the base image
NginxProxyManager/docker-nginx-full#7

There are three Configurations that would be needed to be configurable from Nginx Proxy Manager to configure the crowdsec-openresty-bouncer for the bare minimum to get it working

File: /data/crowdsec/crowdsec-openresty-bouncer.conf

#Enables/Disables the Proxy (true|false)
ENABLED=false
#URL to the crowdsec api
API_URL=
#APIKEY to the crowdsec api, generated on crowdsec using `cscli bouncers add NPM`
API_KEY=

I'm not really sure how to do the frontend, if I can get some guidance I could do it as well

This is also currently a global setting so if an IP is banned it won't be able to connect to any host.

Full config for crowdsec

ENABLED=true
API_URL=http://localhost:8080

CACHE_EXPIRATION=1

# live or stream

Due to the discussion here
jlesage/docker-nginx-proxy-manager#238

I will be reworking this with the final goal that it will be configurable using Nginx Proxy Manager instead of a custom advanced addon that is its current state.

I will also need to update the base image pull request to include the package instead of downloading it the current way.

Updated the initial pull request with new information and reworked this deployment so its possible to be integrated into NPM

@jc21 any update on this? I'm not sure of the status of V3 should this be more focused on that release?

If you need anything more from myside please let me know.

Reopened this in another PR due to the force push closing this one
