Build Cop: include enough information for making a report actionable about repo-automation-bots

[tbpg]

The build URL is configured here: https://github.com/GoogleCloudPlatform/python-docs-samples/blob/master/.kokoro/tests/run_tests.sh#L117

So, you can change it to whatever URL you prefer.

Perhaps we should allow more than one URL, that way we could have public and private links to logs?

If we're able to generate multiple URLs, perhaps construct a history search URL as well so we can see the trend of a failing test over time (flakes, execution time, etc)?

You should theoretically be able to put markdown into the URL field -- I haven't tried it. But, you can almost definitely just do space-separated links and have it work.

If an issue gets closed and the test fails again, the bot will reopen the issue. So, I don't think we need a link for history.

I updated the logs field to include links to Build Status and Sponge. For example, see GoogleCloudPlatform/python-docs-samples#2894 (comment). Marking this as fixed.
