Description

On Python 2 warnings.warn() expects a message that can be coerced to a str.

Python 2.7.10 (default, Oct 14 2015, 16:09:02) 
[GCC 5.2.1 20151010] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import warnings
>>> warnings.warn(u'清')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/warnings.py", line 33, in _show_warning
    file.write(formatwarning(message, category, filename, lineno, line))
  File "/usr/lib/python2.7/warnings.py", line 42, in formatwarning
    s =  "%s:%s: %s: %s\n" % (filename, lineno, category.__name__, message)
UnicodeEncodeError: 'ascii' codec can't encode character u'\u6e05' in position 0: ordinal not in range(128)

BaseCache.validate_key() ​fails to create a proper `message` by using "%s" to interpolate the key into the message instead of using "%r".
