Secret PUT fails with a 500 error

[Douglas Mendizábal]

During a Secret PUT with Content-Type: application/octet-stream, Barbican attempts to decode the binary data to UTF-8. This throws an exception when the binary data contains bits that do not represent a UTF-8 code point.

    Fix a bug with handling of binary data

    When checking the length of the data in a request, Barbican assumes
    that data is UTF-8 encoded strings. Barbican then attempts to
    decode all data from UTF-8 to byte strings, which results in an
    exception when the data does not conform to UTF-8.

    This CR also adds the six library as a dependency to add type checking
    that is compatible in both Python 2 and 3.
