commit 526043b586da0201fd7e374197139e75b249e299
Author: Benjamin Bannier <bb...@apache.org>
AuthorDate: Wed Sep 18 11:37:10 2019 +0200

    Added check script to check for license headers.
    
    This check adds a script which validates that source files have valid
    license headers. This will allow us to reuse this functionality with
    e.g., the pre-commit tool.
    
    At the moment the code added here is not invoked from
    `support/mesos-style.py` since it will be removed in a follow-up commit.
