    Only log text strings in requests

    As was exposed by object_store.create_object, we were attempting to mix
    text and bytes in log messages, which was causing _logger.debug to choke
    when combining the parts of the message, specifically the --data piece.

    This is an issue for two reasons:
    1. It's binary data in general
    2. It's a very large amount of binary data

    The fix is to not log byte strings that come in as `data` unless we can
    decode them to ascii. This will allow us to continue logging some data
    such as auth credentials, but we won't be logging megabytes or gigabytes
    worth of binary data - such as objects being uploaded to Swift - into
    the log file.
