Support for Strict-Transport-Security HTTP on API server

Is there an option to enable HSTS on the cfssl serve command ?

Strict-Transport-Security (https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Strict-Transport-Security) HTTP response header

Kind regards

Start with the cfssl serve command and the linked MDN description of the Strict-Transport-Security response header. Determine where serve options and HTTP responses are handled, then verify that the requested option enables the header on API responses and that its behavior is covered by the relevant existing tests.
