New output plugin: logstash-output-azure_loganalytics

Hi
I would like to contribute a new logstash output plugin, logstash-output-azure_loganalytics. The plugin can be found here:
https://github.com/yokawasa/logstash-output-azure_loganalytics

The plugin makes possible to store logs in Azure Log Analytics, a managed log analysis service that helps you collect and analyze logs generated by resources in your cloud and on-premises environments. Please add the plugin to the logstash-plugins project if you find it useful
