in Python2, ConfigParser is almost the same as RawConfigParser, which
allows set non-string values, but in Python3, ConfigParser.set() only
accepts strings as value of option.
since we do not use "cpar" as an internal storage for options, it does
not matter what type of options we set using ConfigParser as long as it
can be consumed by tempest. boolean settings are translated to "true" or
"false". see also

in Python3, some methods offered by `string` module are now member
method of `str` class, and `string.uppercase` is renamed to
`string.ascii_uppercase` in Python2 and Python3. so let's update
accordingly.

`s` comes from `rgwadmin()`, which passes `StringIO` as stdout, so the
the output should an instance of `str` in both Python2 and Python3.
hence there is no need to decode it using UTF-8 codecs again.

this change partially reverts e46eb8348e.
xattrs could contain non-utf8 encoded data, and should be captured using
BytesIO. moreover, it will be fed to `ceph-dencoder`, which expects
binary when performing "import".

since dashboard is now xrange-free, there is no need to have
xrange-builtin in whitelist, moreover, in python3 the error message
cannot be emitted at seeing xrange.

in python2, dict.values() and dict.keys() return lists. but in python3,
they return views, which cannot be indexed directly using an integer index.
there are three use cases when we access these views in python3:
1. get the first element
2. get all the elements and then *might* want to access them by index
3. get the first element assuming there is only a single element in
the view
4. iterate thru the view
in the 1st case, we cannot assume the number of elements, so to be
python3 compatible, we should use `next(iter(a_dict))` instead.
in the 2nd case, in this change, the view is materialized using
`list(a_dict)`.
in the 3rd case, we can just continue using the short hand of
```py
(first_element,) = a_dict.keys()
```
to unpack the view. this works in both python2 and python3.
in the 4th case, the existing code works in both python2 and python3, as
both list and view can be iterated using `iter`, and `len` works as
well.
