The 'message' class member in Exception was deprecated in PY2.6 and removed in PY3.0 [1]. Should Neutron code abandon its use of this field, it will break current Octavia code. This patch shields Octavia of such change, replacing exc.message calls with exc.__str__(). [1] - https://www.python.org/dev/peps/pep-0352/ Change-Id: Ia7836f0d68e20d9964334bc41f7789efd1007939
