[pca] supplevel option

[Martin Paul]

As the method which PCA uses to determine the support levels for an MOS Account 
with the "--supplevel" doesn't work anymore for 2 months now, and as I found no 
other method to query the required information, I see no alternative to 
deprecating this option.

I've already made the required changes in the current development version:

   $ ./pca --supplevel
   DEPRECATED: Oracle broke the interface to query this information
   $

Too bad.

Martin.
