nfs-utils in Fedora 30 and later switched its configuration
file from /etc/sysconfig/nfs to /etc/nfs.conf, providing a
conversion service (nfs-convert.service) for upgrades.
However, for new installs the original configuration file
is missing. This change:
* adds a tuple-based osinfo.version_number method to handle
more kinds of OS versioning schemes
* detects RHEL and Fedora versions with the the new nfs-utils
behavior
* avoids backing up the new NFS configuration file as we do
not have to modify it.

Add absolute_import from __future__ so that pylint
does not fail and to achieve python3 behavior in
python2.
