Check tor for new capabilities
The integration tests should check our tor instance to see if it has capabilities that stem doesn't (for instance, new GETINFO options or events). If this check fails then it should give a message like "if you're running the latest version of stem then please file a ticket on trac.torproject.org". The server_descriptor and extrainfo_descriptor integ tests both have testing output that could make use of this.
