Request new repo for IBM-specific code

[Joseph Reynolds]

What is the right repository for a new Linux-PAM module to implement an 
IBM-specific ACF authentication?

The access control file (ACF) design was introduced to the OpenBMC 
security working group and is described in [IBM issue 1737][] and 
further explained in [IBM issue 2562][].

Note the [pam-ipmi modules][] are scoped to the OpenBMC project because 
the IPMI implementation is shared by all of OpenBMC.  By comparison, the 
proposed ibm-pam-acf module is intended only for IBM Enterprise 
systems.  The intended implementation is based on standard cryptography 
techniques and could be developed into a general authentication 
solution, but the ACF is specific to IBM in terms of its exact format 
and content, and I expect it will only be used by IBM and its partners.

Can we create a new OpenBMC repo for this?  Perhaps ibm-pam-acf?  Or 
should this go into some other repo?
