shebangs changed from /usr/bin/python2 to /usr/bin/python3.
(Reminder, various distribution packaging guidelines require use
of explicit python version and don't allow '#!/usr/bin/env python',
regardless of how handy that idiom may be.)

glusterfs.spec(.in) package python{2,3}-gluster and python2 or
python3 dependencies as appropriate.

configure(.ac):
+ test for and use python2 or python3 as appropriate. If build
  machine has python2 and python3, use python3. Override by
  setting PYTHON=/usr/bin/python2 when running configure.
+ PYTHONDEV_CPPFLAGS from python[23]-config --includes is a
  better match to the original python sysconfig.get_python_inc().
  All those other extraneous flags breaks the build.
+ Only change the shebangs once. Changing them over and over
  again, e.g., during a `make glusterrpms` in extras/LinuxRPM
  just sends make (is it really make that's looping?) into an
  infinite loop. If you figure out why, let me know.
+ Oldest python2 is python2.6 on CentOS 6 and Debian 8 (Jessie).
  Everything else has 2.7 or 3.x
+ logic from https://review.gluster.org/c/glusterfs/+/21050, which
  needs to be removed/merged after that patch is merged.

Builds on CentOS 6, CentOS 7, Fedora 28, Fedora rawhide, and the
mysterious RHEL > 7.
