config: return extra fields in summary listing of collection

[Hampapur Ajay]

Currently accessing a collection in contrail-api without the detail=True query parameter only returns fq_name, href, uuid fields for each element in the collection.

In scale situations, it is useful to access a (or a set of) particular field(s) more efficiently by a summary list but with some extra fields.

So the REST api would appear as:

GET /<collection-type>?fields=<field1>,<field2>

and would return these fields too for every element in collection (if present).

config: Add support for extra fields in summary listing

Allow extra fields to be returned (in addition to fq_name, href,
uuid) by using a fields query parameter to list URL

In addition fix a bug where boolean fields with False would
never be sent to server by checking for 'is None'.
