Hi!

Elasticsearch can be used as logstash-output using wildcard certificates (HTTPS) ?

`Failed to install template: hostname in certificate didn't match: <es2.DOMAIN> != <*> OR <DOMAIN> OR <*.DOMAIN> OR <es1> OR <es2> {:level=>:error}`

Certificates with multiple domains (SANs) work well, there are only problems when using wildcards.
