Deprecated platform.linux_distribution() and platform.dist()

[damon-atkins]

Description of Issue/Question

http://bugs.python.org/issue1322 platform.linux_distribution() and platform.dist() is being deprecated. The recommendation is to use https://pypi.python.org/pypi/distro instead of platform.linux_distribution() and platform.dist() (https://github.com/nir0s/distro)

It's being removed as it updates far to often to be within the core python code due to changes made in Linux distributions.

Python Versions

Python 2.6 onwards platform.dist() has marked as deprecated
Python 3.7 onwards will no longer have platform.linux_distribution() and platform.dist()

Code within Salt

./grains/core.py:# /etc/DISTRO-release checking that is part of platform.linux_distribution()
./grains/core.py:             platform.linux_distribution(supported_dists=_supported_dists)]
./grains/core.py:        # so that platform.linux_distribution() does the /etc/lsb-release
./version.py:        lin_ver = platform.linux_distribution()
./version.py:        ('dist', ' '.join(platform.dist())),

@damon-atkins thanks for the heads up on this. Looks like we need to get this fixed up especially before we move entirely to python 3 :)
