    Support to use barbican to encode vim password

    1. Add new option 'use_barbican' in config file [vim_keys] section,
       default value is False for Pike.
    2. Use fernet to encrypt vim password, and save the fernet key into
       barbican as a secret.
    3. Add new fields 'key_type', 'secret_uuid' into VimAuth.auth_cred
       json string. secret_uuid is masked in vim-show or vim-list response.
    4. Set the vim's default 'shared' value to False,
       vim can only be used by who created it.
    5. Add a devref to show how to test.
