Nginx Brotli Module Update To Fix 100% CPU Load Issues

Centmin Mod 123.09beta01 and newer has Nginx with optional Nginx Brotli HTTP compression support via Google's ngx_brotli module which you can enable as outlined at How to use Brotli compression for Centmin Mod Nginx web servers. However, some folks reported that enabling ngx_brotli Nginx module would cause high 100% cpu load issues. The issue has apparently been fixed now in latest ngx_brotli module commit.

With the added update I made today, the Nginx version command (nginx -V) will output a build tag which also displays ngx_brotli module's latest commit hash so you can check if you have latest ngx_brotli module updates built for Centmin Mod Nginx binary

---

Example below where (170420-163956-centos7-b23bcb7-br-bcceaab) is the build tag which now shows data stamp 170420 for April 17, 2020 build from Centmin Mod commit b23bcb7 from commit history at centminmod/centminmod and because NGINX_LIBBROTLI='y' was enabled as per instructions, also shows bcceaab which at time of writing is latest commit from ngx_brotli history at google/ngx_brotli. This makes troubleshooting easier as you know the state of the Nginx version built.
