We would like to have filebeat use SNI when connecting to our server. We reach our server via the [aaa.com](http://aaa.com) domain, but it only has a TLS cert for [bbb.com](http://bbb.com). We would like to tell filebeat to connect to the server using [aaa.com](http://aaa.com), but to expect a cert for [bbb.com](http://bbb.com) when performing a TLS handshake.

I was thinking this might look something like:

```auto
output:
    elasticsearch:
        tls:
            server_name: "bbb.com"

```

and then the parameter would get slotted into [https://github.com/elastic/beats/blob/master/libbeat/common/transport/tlscommon/config.go#L87](https://github.com/elastic/beats/blob/master/libbeat/common/transport/tlscommon/config.go#L87) somehow.

I am happy to write the patch - would it be likely to be accepted? Thanks!

Hi Elastic team - what do I need to do to move this along? The CONTRIBUTING guide for Beats told me to ask here before starting work on my feature. Thanks.
