Review request for mesos and Kevin Klues.
Bugs: MESOS-9075
https://issues.apache.org/jira/browse/MESOS-9075
Repository: mesos
Description
-------
The switch from Python 2 to Python 3 creates problems regarding the
virtual environment if a developer dangles between Python 2 and 3 as
we want the virtual environment to use the same version of Python as
the user to give useful logs when linting.
This commit fixes the issue by adding a new check in the function of
`mesos-style.py` called `should_build_virtualenv` to see if the Python
interpreter version currently used is the one in the virtual
environement. If not, the virtual environment will get recreated.
A second issue was that running `build-virtualenv` with Python 3
then again with Python 2 would end up with two versions of Python
in the virtualenv and continue to use Python 3 in that environment.
This is due to an old issue of `virtualenv` that we now handle by
removing the entire virtual environment before building it again.

Testing
-------
Run the two `mesos-style.py` and `build-virtualenv` with `MESOS_SUPPORT_PYTHON`
set to 3 or not. Checked that the python intepreter installed in the virtual
environment was correct.
Thanks,
