***Note from Migration:***
Original Title was: Extend the HttpCaller with an option to create a secure connection with a certificate
Please add an option to enable HttpCaller to create a secure SSL connection using a custom X.509 certificate.
Preferably enable providing the certificate in multiple format formats, e.g. both certificate/key separated formats and the joined format of pkcs12.
I can provide sample code that works in a PythonCaller (Python 3.7+).
