Status exit code

When /etc/init.d/solr status is called and solr service is not running, the return exit code is 0 instead 3.

I made some modifications in the /opt/solr/bin/solr file to correct this issue:

• after line 446: add "exit 3"
• after line 466: add "exit 3"

This issue appeared with an industrialisation configuration tool (puppet in my case) which check if service is running.
