Our benchmark job starting failing when we stopped supporting Python 3.5
and 3.6, but this change fixes it by running it in our java_stretch
Docker container, which has a more recent Python version. I also deleted
all configs related to old Python versions that we no longer support.
* Set execute bit on files if and only if they begin with (#!).
Git only tracks the 'x' (executable) bit on each file. Prior to this
CL, our files were a random mix of executable and non-executable.
This change imposes some order by making files executable if and only
if they have shebang (#!) lines at the beginning.
We don't have any executable binaries checked into the repo, so
we shouldn't need to worry about that case.
* Added fix_permissions.sh script to set +x iff a file begins with (#!).
