In CAPC when clicking next to a data collector in the data collector list we do
not see the associated devices in the lower pane.  An exception like
"HTTP 413 Error Code. Requested Entity is too large" would be seen in the
DA karaf.log
Any CAPM environment
The REST call do show the list of devices is to large
1. Create a file named :
     in the DA's INSTALL_ROOT/apache-karaf-XXX/etc/ directory.
2. Add the following line to that file
    maxReturnItemCount=500001 (example)
3. The exact number that you put in should mimic the approximate
count seen in the DA karaf.log, with the caveat that setting this to a
high number can result in OutOfMemory errors.
