+HPA & Cloud Agnostic Intent

Constrain each demand's inventory candidates based on cloud regions' Hardware

+platform capabilities (HPA) and also intent support. Note that currently HPA

Requirements mapped to the inventory provider specified properties, referenced
by the demands. For eg, properties could be hardware capabilities provided by

| Property | Value |
+===============+========================================================+
-| ``evaluate`` | List of flavorLabel, flavorProperties of each VM of the|
-| | VNF demand. |
+| ``evaluate`` | List of id, type, directives and flavorProperties of |
+| | each VM of the VNF demand. |
+---------------+--------------------------------------------------------+
++-------------------------+--------------------------------------------------------+
+| Property for evaluation | Value |
++=========================+========================================================+
+| ``id`` | Name of VFC |
++-------------------------+--------------------------------------------------------+
+| ``type`` | Type of VFC. Could be ``vnfc`` or ``tocsa.nodes.nfv. |
+| | Vdu.Compute`` according to different models |
++-------------------------+--------------------------------------------------------+
+| ``directives`` | Directives for one VFC. Now we only have flavor |
+| | directives inside. Each VFC must have one directive |
++-------------------------+--------------------------------------------------------+
+| ``flavorProperties`` | Flavor properties for one VFC. Contains detailed |
+| | HPA requirements |
++-------------------------+--------------------------------------------------------+
+
++--------------------------+-------------------------------------------+
+| Property for directives | Value |
++==========================+===========================================+
+| ``type`` | Type of directive |
++--------------------------+-------------------------------------------+
+| ``attributes`` | Attributes inside directive |
++--------------------------+-------------------------------------------+
+
++--------------------------+-------------------------------------------+
+| Property for attributes | Value |
++==========================+===========================================+
+| ``attribute_name`` | Attribute name/label |
++--------------------------+-------------------------------------------+
+| ``attributes_value`` | Attributes value |
++--------------------------+-------------------------------------------+
+
+*Note*: Each VFC must have one directive with type 'flavor_directives' to put the
+flavors inside. The ``attribute_name`` is the place to put flavor label and the
+``attribute_value`` will first left blank. After getting the proper flavor, OOF will
+merge the flavor name into the ``attribute_value`` inside flavor directives. Also,
+all the directives coming from one VFC inside the same request will be merged
+together in ``directives``, as they are using the same structure as 'directives'.
