Modified pegasus-monitord so that it does not require the PYTHONPATH and PEGASUS_HOME to be set. The code first tries to derive the path to Pegasus' Python library from the PEGASUS_HOME environment variable. If PEGASUS_HOME is not set, it will try to figure out PEGASUS_HOME based on the location of the pegasus-monitord binary, and then add the lib/python directory to Python's search path. This is related to JIRA issue PM-197
