lbaas data model is too recursive

[YAMAMOTO Takashi]

this is an example of pool to_api_dict().
http://paste.openstack.org/show/589872/
as you can see, it has too many copies of same objects.
note: there are only 3 objects in the dict.

while from_sqlalchemy_model has some recursion protection,
it's better to make it shallower.

especially, to_dict/to_api_dict should not do much recursion.

I consider that this affects the payload of the object and not the current functionality.

[YAMAMOTO Takashi (yamamoto)]

Victor,

i consider this high priority as it affects driver api.
but it might be just me.
