Insecure ssl support?

[jinserk]

Hi,

I've tried to make kafka-connect-elasticsearch work with opensearch, and happen to know this project. I wonder this connect is support the default opensearch's docker image which is enabled the secure plugin. The secure plugin setup the ssl but not the cert verification, so we need to add insecure option unless we setup the ssl keys. It'll be the best if this connect support such "insecure" ssl mode.

Thank you!

Hi, I removed insecure, as it's usually a pretty bad habit to use it, and getting certificates, even for development environments is quite easy these days. I'm not opposed to a PR adding it back though.
