    Support new hashing algorithms for securely storing password hashes
    
    Support bcrypt, pbkdf2_sha512, or scrypt in password hashing for
    passwords managed within keystone. sha512_crypt is insufficient to
    hash passwords in a secure way for storage in the DB. Keystone defaults
    now to using bcrypt but can handle scrypt and pbkdf2_sha512 with a number
    of tuning options if desired.

Bug description:
  Keystone uses sha512_crypt for password hashing. This is insufficient
  and provides limited protection (even with 10,000 rounds) against
  brute-forcing of the password hashes (especially with FPGAs and/or GPU
  processing).

  The correct mechanism is to use bcrypt, scrypt, or pbkdf2_sha512
  instead of sha512_crypt.

  This bug is marked as public security as bug #1543048 has already
  highlighted this issue.
