Bug description:
  In nova, hypervisor view builder's collect_name is 'hypervisors':

  ```
  # nova.api.openstack.compute.views.hypervisors.ViewBuilder
  class ViewBuilder(common.ViewBuilder):
      _collection_name = "hypervisors"
   
      def get_links(self, request, hypervisors, detail=False):
          coll_name = (self._collection_name + '/detail' if detail else
                       self._collection_name)
          return self._get_collection_links(request, hypervisors, coll_name,
                                            'id')
  ```

  So when we do paginated query via openstacksdk, we would get response
  like this:

  ```
  {u'hypervisors': [{u'status': u'enabled', u'state': u'up', u'id': u'53fb5bdc-f9a4-4fc4-a4be-8eb33cd236b1', u'hypervisor_hostname': u'gd02-compute-11e115e64e19'}, {u'status': u'enabled', u'state': u'up', u'id': u'a4db6ea8-2a91-45e7-a4b4-cb26c2dbc514', u'hypervisor_hostname': u'gd02-compute-11e115e64e11'}, {u'status': u'enabled', u'state': u'up', u'id': u'd92c5452-ea75-4f58-8e0b-b4a6823850d8', u'hypervisor_hostname': u'gd02-compute-11e115e64e12'}], u'hypervisors_links': [{u'href': u'http://nova-api.cty.os:11010/v2.1/hypervisors?limit=3&marker=d92c5452-ea75-4f58-8e0b-b4a6823850d8', u'rel': u'next'}]}
  ```

  And openstacksdk uses wrong hypervisors_links to query next page, and
  get error:

  ```
  Traceback (most recent call last):
    File "p_hypervisors-admin.py", line 48, in <module>
      do_operation(limit, marker)
    File "p_hypervisors-admin.py", line 38, in do_operation
      srvs = [i for i in info]
    File "/usr/lib/python2.7/site-packages/openstack/resource.py", line 898, in list

  ```

  The right uri should be `/v2.1/os-hypervisors`
