Jan Gutter c90081bb94 Clean up versioned object backlevelling code 
The backlevelling code for the VIF objects have a number of sharp edges.
This commit changes the layout of the obj_make_compatible methods to conform
to a fixed pattern.

Given the following version history:

 # Version 1.0: Initial Release based on ParentClass 1.0
 # Version 1.1: Added member_one_one
 # Version 1.2: ParentClass version increased to 1.1 from 1.0
 # Version 1.3: Added member_one_three
 # Version 1.4: ParentClass version increased to 1.2 from 1.1
 # Version 1.5: Added member_one_five

Use the following pattern for obj_make_compatible():

 0. use versionutils to calculate target_version

 1. Remove added members from the primitive in reverse order:
    - if target_version < (1, 5) and 'member_one_five' in primitive:
          del primitive['member_one_five']
    - if target_version < (1, 3) and 'member_one_three' in primitive:
          del primitive['member_one_three']
    - if target_version < (1, 1) and 'member_one_one' in primitive:
          del primitive['member_one_one']

 2. Call the parent method explicitly when the parent class caused a version
    bump in this object, in the following if/elif tree:
    - if target_version < (1, 2):
          super(MyClass, self).obj_make_compatible(primitive, '1.0')
    - elif target_version < (1, 4):
          super(MyClass, self).obj_make_compatible(primitive, '1.1')

 3. Finally, if target_version is recent enough, call the parent method with
    the current version of the parent class:
    - else:
          super(MyClass, self).obj_make_compatible(primitive, '1.2')

This pattern has been documented in: https://review.openstack.org/632321/
