NB Upstream EOL is not relevant. We need to base min version changes
on the OS platform support matrix. So it would be better for the
commit message to provide details of the version in the various
distros we target, to show that the min version change is valid.

Python 3.5 is now EOL. Python 3.6 brings with it several nice things: - Literal string interpolation (PEP 498) - Syntax for variable annotations (PEP 526) - Preserving keyword argument order (PEP 468) * PEP 526 in particular will allow us to convert the QAPI module to the statically typed subset of the Python language. These static type hints improve the interactive editing experience in IDEs and help make refactoring and adding new features faster, easier and safer. *Note: **kwargs is now guaranteed to preserve keyword ordering, but dict itself is still allowed to have an arbitrary order based on implementation. It is not until Python 3.7 that the dict type guarantees insertion order.
