Subject: Use six.StringIO/BytesIO instead of StringIO.StringIO
X-Git-Url: https://review.fuel-infra.org/gitweb?a=commitdiff_plain;h=27a72e9d9b878e70c40439fbc3c85e0e285ab135;p=openstack-build%2Fneutron-build.git

Use six.StringIO/BytesIO instead of StringIO.StringIO

to keep Python 3.x compatibility, use six.StringIO/BytesIO to
replace StringIO.StringIO

StringIO works for unicode
BytesIO works for bytes

Closes-Bug: #1280100
