Add support for basic auth to elasticsearch plugins

[florent26]

Hi,
Is it possible to add http auth params on the elasticsearch plugin ?
For example it doesn't work when Xpack Security is enable.

Thanks,

I have tried in /etc/telegraf/telegraf.d :

servers = ["http://elastic:XXXXXX@10.24.0.15:9200"]


But it doesn't work.

Sorry, finally it works with http://USERNAME:PASS@.....

Maybe you just can update the readme ?
Thanks

I think we should add support for HTTP Basic auth which uses the Authentication header instead of the userinfo section of the URL. The reason being that the URL can be printed in a number of circumstances, and many don't want to log credentials. I can add this if you could help test it out, are you working with the Elasticsearch input or output?
