Script to generate CL descriptions when rolling chromium_revision.

Having nice CL descriptions that explains what a roll of
chromium_revision in WebRTC's DEPS file actually changes is
useful to save time tracing down breakages.
This script can be used to generate such CL descriptions.
In the future it might be used for a complete auto-rolling
solution for this.
