Add support for Network QoS rule commands

Added following commands:
  - network qos rule create --type minimum-bandwidth
                                   dscp-marking
                                   limit-bandwidth
  - network qos rule delete
  - network qos rule list
  - network qos rule set
  - network qos rule show

+================
+network qos rule
+================
+
+A **Network QoS rule** specifies a rule defined in a Network QoS policy; its
+type is defined by the parameter 'type'. Can be assigned, within a Network QoS
+policy, to a port or a network. Each Network QoS policy can contain several
+rules, each of them

+network qos rule create
+-----------------------
+
+Create new Network QoS rule
+
+.. program:: network qos rule create

+
+.. option:: --type <type>
+
+    QoS rule type (minimum-bandwidth, dscp-marking, bandwidth-limit)

+
+    Maximum burst in kilobits, 0 means automatic
+
+.. option:: --dscp-mark <dscp-mark>
+
+    DSCP mark: value can be 0, even numbers from 8-56, excluding 42, 44, 50,
+    52, and 54
