change webhook URL and add functionality for each job to post to bot

[bobholt]

This is the PR that will switch from using prbuildbot to the wptdash app. This is dependent on @sideshowbarker completing the GitHub Token setup and updating the vault file in wptdash, but I wanted to get this in front of @jgraham as it includes new check_stability code.

This currently points to the staging server so we can make sure it works before landing. Need to change that before merging.

Almost there. Looks like I need to fix a conditional in the template.

@jgraham I think this is ready to go pending the following:

1. Any further code review you'd like to do
2. Land fix has_unstable check in comment templates pulls.web-platform-tests.org#11
3. Remove -staging from URLs and webhook

I'll do #3 after 1 and 2 because doing that will cause it to start immediately posting to the production server. You can see it populating http://pulls-staging.web-platform-tests.org/ with pulls (but no build data except for this PR) already.

The other open question is SSL. I don't think it should hold us up since there's nothing protected there. I'm working with the infrastructure people on our side to make getting and renewing that certificate free and painless for all, but probably won't have that until next week.

[bobholt]

@jgraham. I've added web-platform-tests/pulls.web-platform-tests.org#12 for SSL support to the dashboard. Do you have any other review on this PR before I switch it to reference the production servers instead of staging?
