Unable to install plugin from GitHub URL

[skbly7 (Shivam Khandelwal)]

I am unable to install Kibana plugin behind proxy (from URL)

The URL is being treated as a package name, which in turn generate artifacts.elastic.co URL and the process fails to download the file.

Kibana Version: 6.3.2.
Kibana Image Repository: docker.elastic.co/kibana/kibana

Am I doing something wrong with the install command? Or it looks like a bug in 6.3.2 version?

Kibana creates a list of urls to try, and goes down the list as failures happen. In this case it is trying the GitHub release first and getting an error.

Can we try downloading the release manually (maybe using curl with the proxy flag) to validate that the proxy can fetch the release? If that does work we can temporarily install using file:/// while we figure out a fix on the Kibana side.
