Running elasticsearch under a subdirectory

[psaiz]

First of all, thanks for the very useful plugin!

I have an issue running the plugin on my cluster. I'm using the same port for kibana and elastic, and then, based on the location, I go to kibana or elastic. In other words, under my web server I have
https://my.host.domain/elastic and https://my.host.domain/kibana .

So, to reach whatson, I go to https://my.host.domain/elastic/_plugin/whatson. Then, the plugin leaves the 'elasticsearch host' box in the settings empty. If I put there https://my.host.domain/elastic, then the javascript appends :9200.

Would it be possible to have a patch like the following:
