Enable PASSTICKET support for the FTP Client

There needs to be an option added to the FTP Client to enable the use of PASSTICKET as an authentication metric. Currently the only options that can be used with FTP Client is Password/MFA or X509 Certificate logon.
The issue with password logon is that in things like batch jobs the password becomes exposed in the dataset or netrc file and is considered a security risk.
The issue with MFA is again with BATCH jobs is if the job is not dispatched fast enough it fails and will not allow it to be run during a particular time period in late night processing.
While Certificates do address the issues mentioned above the additional overhead of maintaining certificates across 15 sysplex environments becomes daunting without something like NSSD to provide support.
Adding this option say a –P allows for FTPClient to create the one time passticket password and the FTP server should not need an update since the RACROUTE call should check to see if the passticket is either a password or passticket.

    This issue has become more relevant during the last few years. The pressure from the business for secure file transfer has only increased. One of the z Series biggest selling point is that it is secure. Well, this is a major weakness that deserves immediate attention. You can say IBM has a secure solution, but it's super difficult to manage. We need a simpler, more robust solution.
    One idea is to have to option to 1) reject in-stream NETRC (//netrc dd *), and 2) enforce NETRC in the second qualifier of the data set name, so the ACS routine could force &DSN = .NETRC.* then SET &DATACLAS= 'NETRC'. NETRC data class would enable data set encryption.
