Even though we should probably avoid using non-standardized HTTP headers, since there is already X-FRAME-OPTIONS present in a management WFCORE-1463, I propose to consider to add also X-Content-Type-Options header in a default configuration of the management too.

Benefit is slightly improved security for customers using Web Console management.

curl -v http://localhost:9990/console/index.html
