    Replace textwrap with fast standard code

    This improves on commit 4350c176048b8d159d08b82b915e9544ac9dee6f

    We found a major performance regression in keystoneclient
    when using PKI tokens, related to http://bugs.python.org/issue25870

    It can be tested with
    time python -c "import textwrap; textwrap.wrap('x'*9000, 64)"

    which has a complexity of O(n*n)
    because it uses certain regexps in python versions before 3.5.
