full of failures under Python 3

[Thomas Goirand]

Building trove-dashboard under Python 3.6 in Debian Sid leads to so many errors. Test log attached.

Please get this resolved, or I will have to get trove-dashboard removed from Debian (as Horizon is already switched to Python 3).

    Fix binascii hexlify under Python 3

    Add wrapper functions for binascii hexlify/unhexlify to deal with the
    conversion between bytes and str.

    Fix str and dict usages in unittests for Python3

    - use six.text_type instead of unicode for assertion;
    - use dict.items() instead of dict.iteritems() for dict iteration;
    - use six.text_type to capture exception messages, the 'message' attribute
      is no longer existing;
    - dict.keys() returns a dict_keys object under Python3 which cannot be
      reversed, explicitly convert it to a list.

    Use for loop instead of map to modify iterables

    Previously we use map() to apply changes to every item in a iterable
    object, but this is not a proper usage. And in Python3, map() will
    return a map iterator object, changes will not be applied immediately,
    as we're not iterating the map object, changes will never be applied.
    Changing to for loop instead fixes.

    Avoid using hasattr() on troveclient resources for py3 porting

    troveclient resources use the lazy-loading feature, which causes problems
    for calling hasttr() on the object. copy.deepcopy() also use hasattr(),
    and results in infinite loops. hasattr() will ignore any exceptions under
    Python 2.x, but reraise them under Python 3, this is reason why the related
    test cases passed under Python 2.x and keep failing under Python 3. This
    patch fixes and should be the last one to fix the py35 gate jobs.
