Remove Support for VixDiskLib 5.1.0

VixDiskLib 5.1.0 has a known bug intermittently causing a
segfault during disk open operations when the vCenter Server
does not provide an SSL thumbprint for the target host.  The
error depends upon the memory content.  This segfault has been
encountered during testing so support for this version has
been removed.  Only this version has this flaw.

Add capability to easily add other unsupported versions along
with a concise reason to be printed to the log.

Locate same named method, instances and classes across domains

    This feature allows the UI to display a list of overridden instances
    and methods from different domains. The functions return a list of
    classes, instances or methods ordered based on domain priority. The
    UI should be able to guide the end user to the highest priority
    classes, instances and methods
