Ticket 49218 - Certmap - inplace upgrade mechanism
    
    Bug Description:  This adds support for pluggable certificate
    mapping libraries. To achieve this, this replaces the existing
    baked in certificate mapping code.
    
    Fix Description: Add an inplace upgrae mechanism that is docker
    compatible. This is important as we can not rely on the ability
    of setup-ds.pl -u  or other external tool to have been run, this
    MUST be internal to the server at start up.
