Data collector not showing device list

Issue/Introduction

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

Environment

Any CAPM environment

Cause

The REST call do show the list of devices is to large

Resolution

1. Create a file named :
    com.ca.im.item.ws.impl.AutomaticWebServiceManagerImpl.cfg
     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.
