    Add resource_class to fields in ironic node cache
    
    Per the discussion in [1], the ironic nodes added to the node cache in
    the ironic virt driver may be missing the required field resource_class,
    as this field is not in _NODE_FIELDS. In practice, this is typically
    not an issue (possibly never), as the normal code path uses a
    detailed list to sync all ironic nodes, which contain all fields
    (including resource_class). However, some code paths use a single
    node query with the fields limited to _NODE_FIELDS, so could result in a
    node in the cache without a resource_class.
    
    This change adds resource_class to _NODE_FIELDS.

Title:
  Ironic virt driver node cache may be missing required fields

Status in OpenStack Compute (nova):
  Fix Released
Status in OpenStack Compute (nova) queens series:
  Confirmed

Bug description:
  Per the discussion in [1], the ironic nodes added to the node cache in
  the ironic virt driver may be missing the required field
  resource_class, as this field is not in _NODE_FIELDS. In practice,
  this is typically not an issue (possibly never), as the normal code
  path uses a detailed list to sync all ironic nodes, which contain all
  fields (including resource_class). However, some code paths use a
  single node query with the fields limited to _NODE_FIELDS, so this
  should be changed to include the required resource_class.

  There are a number of other minor related issues picked up in that
  discussion, which don't really deserve their own bugs:

  * Filter the node list in _refresh_cache using _NODE_FIELDS.
  * Improve unit tests to use representative filtered node objects.
  * Remove _parse_node_instance_info and associated tests.
