[CRIU] CRIU and Python 3

[Adrian Reber]

Python 2.7 will be retired 2020 (https://pythonclock.org/) and as
Fedora might drop Python 2.7 at some point and as RHEL 7.5 says:

 Python 2 will be replaced with Python 3 in the next Red Hat Enterprise
 Linux (RHEL) major release.

Has there been any discussion about using Python 3 in CRIU? I am
currently trying to port a few CRIU things to Python 3 (not zdtm yet)
but wanted to check if somebody did already the work?

For me as a packager it would be nice if we could support Python 2.7 and
Python 3 and I guess it should be possible at least with CRIU and CRIT.
Not sure about zdtm and not really necessary as zdtm is not shipped as
a package for the end user. But it would be nice if the things installed
on an end user system via a package would support both Python versions
for some time.
