DISPATCH-883 - Prevent the router from crashing when the connection properties
is not PN_STRING or PN_SYMBOL or PN_INTEGER. Also added a few system tests
> Router crashes when it processes management request for connections

> Key: DISPATCH-883
> URL: https://issues.apache.org/jira/browse/DISPATCH-883
> Project: Qpid Dispatch
> Issue Type: Bug
> Components: Container
> Affects Versions: 1.0.0
> Reporter: Ernest Allen
> Assignee: Ganesh Murthy
>
> Router crashes when attempting to service a management request.
> When a python client sets its connections properties to a map, then as soon
> as the router receives a management request for the connection info, the
> router will crash.
> If the client sets its connections properties to a string, then there is no
> crash.
> To reproduce:
> - start the router using tests/config-1/A.conf
> - modify the proton example server.py to set a properties map on line 37:
> self.conn = event.container.connect(self.url,
> properties={'client_identifier': 'policy_server'})
> - start the modified proton example: ./server.py -a 0.0.0.0:20000/example
> - all is well until you do a qdstat -b 0.0.0.0:20000 -c
> backtrace:
> Thread 2 "qdrouterd" received signal SIGSEGV, Segmentation fault.
