Every plugin that supports some of QoS rules will define a property
called supported_qos_rule_types of list type.
For ml2, determine supported qos rule types as a subset of rule types
supported by all drivers. (In the future, we may expand the list to
include all types supported by at least one of enabled drivers. This
would require synchronized work with nova scheduler though.)
For ml2, tests are limited, and should be expanded to check that common
subset of qos rules is calculated properly when intersection != the list
of each plugins. For now, it's enough since we don't have more than one
rule type planned for Liberty.
Added API test for the resource.
