Description:
testservice: version/network/details support

These changes are for juju-core project testing. They include new API
endpoints:

- /version/
   return capabilities, currently only networks-management
- /network/<name>/?op=list_connected_macs
   returns list of MAC addresses connected to a network
- /nodes/<system_id>/?op=details
   returns lshw XML as application/bson, the XML data should be added
before with AddNodeDetails(systemId, xml) function

Now for API endpoint:
   /networks?node=system_id
TestService returns empty list if node is not found or no networks are
connected to the node.
It panicked before.
