Mutual tls/ssl on elasticsearch

Hi @ikakavas,

I have gone through the above links already. Mutual SSL authentication is the concept of two parties authenticating each other at the same time. So the client has to provide its own identity to the server and in the same manner server must provide its own identity to the client.

I want to enable mutual tls between elastic cluster and other clients, in my case client is our own standalone developed api. So how to do that ?
Correct me if I am wrong - If i add the above mentioned lines in yml files, i guess it is one way tls.

Please help me on this. Thanks!
