Manual release for SonarQube 7.2-7.3 including :

I have released on my fork a working version of this plugin including several pull requests of @brunopadz @zhuopeng @gmilosavljevic @dbsanfte @bitzl and @el95149.

I also have upgraded the plugin to make it working with 7.2 and 7.3 APIs.

I have replaced the webhook call to use OkHttp directly to offer proxy features.

Can you merge it ? If you don't have time or motivation, please tell it to me, I may maintain the plugin;

Best,

Sylvain
