Papertrail sends requests with the content type
`application/x-www-form-urlencoded`, with the payload parameter holding the
JSON body. This commit fixes the papertrail integration to use the payload
parameter in the request's POST data instead of trying to parse the
request's entire body as JSON.

Previous cleanups (mostly the removals of Python __future__ imports)
were done in a way that introduced leading newlines. Delete leading
newlines from all files, except static/assets/zulip-emoji/NOTICE,
which is a verbatim copy of the Apache 2.0 license.

This commit migrates all of our webhooks to use
check_send_webhook_message, except the following:
beeminder: Rishi wanted to wait on this one.
teamcity: This one is slightly more work.
yo: This one is PM-only. I am still trying to decide whether we
should have a force_private argument or something in
check_send_webhook_message.
facebook: No point in migrating this, will be removed as part of
#8433.
slack: Slightly more work too with the `channel_to_topics` feature.
Warrants a longer discussion.
