nginx-ntlm-module module support

[jens-maus]

This PR adds https://github.com/gabihodoroaga/nginx-ntlm-module to the openresty build to address the following long-standing issues by implementing basic support for NTLM based single-sign-on proxying using nginx proxy manager:

NginxProxyManager/nginx-proxy-manager#1117
NginxProxyManager/nginx-proxy-manager#1138
NginxProxyManager/nginx-proxy-manager#2037
NginxProxyManager/nginx-proxy-manager#3181
NginxProxyManager/nginx-proxy-manager#3797

In practice, the following steps are then required to get NTLM authentication successful running with NPM:

1. add the following section to the /data/nginx/custom/root_top.conf file to load the module:

load_module /usr/lib/nginx/modules/ngx_http_upstream_ntlm_module.so;

2. add the following to the /data/nginx/custom/http.conf file to define the NTLM aware upstream target:

upstream target {
  server 192.168.1.1:443;
  ntlm;
}

3. add the following to the proxy configuration in the Advanced tab:

location /  {
  proxy_http_version 1.1;
  proxy_set_header Connection "";
  proxy_pass https://target;
}

Then, the NTLM authentication should proceed and work nicely.

P.S.:
As a side note for users which cannot wait until a new nginx proxy manager version with this integrated NTLM module is out, one can also simply compile it using the docker-nginx-full repository and the local-build.sh script, then extract the ngx_http_upstream_ntlm_module.so file and put it into e.g. the /data/nginx/modules path and simply use the following load_module call in step 1 instead:

load_module /data/nginx/modules/ngx_http_upstream_ntlm_module.so;
