SKRBKDC: Support for switching off Replay Detection

We've an application on OSCP. Our security policy says that from docker against z/OS Kerberos have to bee used for authentication.

Actually, per server are multiple instances of docker running / per docker multiple threads. Each thread goes against z/OS. Now, we are getting more and more load on the Dockers and so on the Kerberos KDC on z/OS. This results in massivly Replay Detection Errors within CICS.

We know Replay Detection is a security feature. But it should be possible to switch it off. Changing the application so that multiple gss_init_sec_context()s are done results in massive overhead on the z/OS site.
