- when downloading the internal job binaries, compare it
with the original file;
- simplify the string matching for the error messages in negative
testing (job binary and node group templates). The returned string
is a bit different when using python 3 (few \n remainings, maybe
there is an interaction between string and byte arrays.)
- run the API v2 tests using Python 3. Python 3 and API v2 tests
have been both added in Stein.
- define few data strings used for testing as bytes, so that they
can work with both Python 2 and Python 3.
