    Hash functions support different hash algorithms
    
    The token hash functions always used MD5. With this change, the
    hash function can be passed in to the hash functions.

Title:
  Keystone token hashing is MD5

Status in OpenStack Identity (Keystone):
  In Progress
Status in OpenStack API documentation site:
  Confirmed
Status in Python client library for Keystone:
  In Progress

Bug description:
  https://github.com/openstack/python-
  keystoneclient/blob/master/keystoneclient/common/cms.py

  def cms_hash_token(token_id):
      """
  return: for ans1_token, returns the hash of the passed in token
  otherwise, returns what it was passed in.
  """
      if token_id is None:
          return None
      if is_ans1_token(token_id):
          hasher = hashlib.md5()
          hasher.update(token_id)
          return hasher.hexdigest()
      else:
          return token_id

  
  MD5 is a deprecated mechanism, it should be replaces with at least SHA1, if not SHA256.
  Keystone should be able to support multiple Hash types, and the auth_token middleware should query Keystone to find out which type is in use.
