config-perf: fallback to list with POST when query params too large in GET

[Hampapur Ajay]

In scaled setup it was observed that neutron net-list issues a subnet-list(with 203 ids) with query-params exceeding the default 8192b in haproxy (keystone token size itself is significant).

To overcome this
1. python library should transparently fall-back to getting this list via a POST operation where body will have the 'query-params' content
2. api server should expose a POSTable URI to get bulk lists

config-perf: handle list with large query-param size with POST

api-library adds a resource_list method to query a collection.
This method GETs on type-specific URI if query-params is not too
large, else falls back to POST on generic URI.
api-server adds a list-bulk-collection action URI. Fixes the
BaseRequest size so large POST bodies can be handled.

Tests for querying by anchor of parent_id list, anchor of
back_ref_id list and obj_uuids list.
