Add add_codereview_message.py script. This script takes a message and
a codereview URL as arguments calls `git cl upload` to append the
message to the given codereview issue.
Motivation: We are automating a process of testing Chromium/Skia DEPS
rolls where roll_deps.py is automatically run every night, and then at
a later time, compare_codereview.py is run to generate a report of the
trybot results. This script can be used to append that report to the
DEPS roll Cl.
This CL also refactors functioanlity common to roll_deps and
add_codereview_message:
* Add tools/git_utils.py module.
- ChangeGitBranch class was factored out of
roll_deps.GitBranchCLUpload. The other half of that class
became roll_deps.git_cl_uploader function. I make use of
this new class in both roll_deps and upload_deps_roll.
- test_git_executable moved to this new module.
* Add tools/misc_utils.py - move VerboseSubprocess, ChangeDir,
and ReSearch classes from roll_deps module.
* Remove generic functions from roll_deps.
* Add git_cl_uploader function to roll_deps. Refactor
roll_deps.roll_deps function to make use of it
