Improve manage.py to automate CL creation further.

Improve manage.py to automate CL creation further.

It's tedious to write CL description manually. Make manage.py make the CL
description for me.

This permits me to create CLs like https://codereview.chromium.org/1200263002 in
record time. This also makes the CL description much more informative that it
would be if I were to manually write it.

File testing/buildbot/manage.py (right):

https://codereview.chromium.org/1203753002/diff/1/testing/buildbot/manage.py#...
testing/buildbot/manage.py:197: data['count_run_on_swarming'])
this formatting is a bit odd; why isn't the string on the first line?

"%d configs already ran on Swarming" maybe?
