Configures global system properties on the JSSE implementation, if defined.
WARNING: This class sets system properties to configure JSSE code which typically uses static initialization on
load. Because of this, if classes are loaded in BEFORE this code has a chance to operate, you may find that this
code works inconsistently. The solution is to set the system properties on the command line explicitly (or in the
case of "ocsp.enable", in the security property file).
For use in testing.
