model/neutron extension: add configuration string

Add configuration string to neutron-extension-attribute.
So that ODL openstack service provide can negotiate with networking-odl
about more details on each extension.
For example, neutron QoS API needs supported QoS rules.
key" "neutron:qos"
configuration: {"supported_rules_types": ["bandwidth-limit"...] }
Also neutron-extension can be used for general negotiation between
ODL and networking-odl. e.g. port::status update is supported etc.
key: "ODL:status-update"
configuration: ["network", "port", "router", ...]

TODO: coordinate/document key/configuration in central places.
