Title:
  name validate check is necessary for neutron-core

Status in OpenStack Neutron (virtual network service):
  Fix Released

Bug description:
  So far, the validate of name when creating network subnet and port is not functional.
  This is because the validate attribute of name in the RESOURCE_ATTRIBUTE_MAP of neutron/api/v2/attributes.py is set to "None".
  When user inputs a more than 255 length name on purpose, an internal DB Error will return.

  ===========================

  It is better for neutron to return something like 400 Bad Request Error instead of internal DB Error.
  The validate of name length should be limited to 255.
