Release tags do not live on master: 3.15.2 through 3.15.6 were tagged on branch
3.15, so git describe reaches only 3.15.1 and dev builds were stamped
3.15.2.dev<n>. Besides being confusing, rpm and dpkg both rank the released
3.15.6 above that, so a dev package will not install over a released one.
Add a top-level VERSION file naming the release the branch is working toward
(4.0.0 on master) and a mkversion helper that stamps packages from it, keeping
the tag-derived value as a floor so a forgotten bump cannot go backwards.
mkversion also replaces the block copy-pasted into seven build scripts, and
makesetup no longer writes a per-package VERSION file, so the stale checked-in
confluent_common/VERSION goes with it.
The source distrobution on CentOS7 does not work well
with python2. Using python3 to build the dist for python2
and python3 fixes issues with extra data being missed in
packaging.
