With this commit most of the Python 3 compatibility issues in murano-engine are resolved. If run on yaql with https://review.openstack.org/#/c/286110/ fix all of the unit tests except for one success. The only failing test is base64 encoding/decoding test which require rethink of resource management to get away from string types for binary content Change-Id: Iee87d27fe4f04118202de07f376d41fbf2c90f54
