To be able to get a screenshot of the personal message using the
`generate-integration-docs-screenshot` tool, this commit changes the
personal build to be triggered by iago, instead of cordelia.
The TeamCity webhook plugin supports multiple payload formats that
are customized to be used by different services such as Slack,
Flowdock, etc. We don't support such payloads, so we should ignore
them and stick to parsing only the generic ones. We should also
notify that bot owner about the error.
All webhook fixtures in zerver/fixtures/<webhook_name> have now
been moved to dedicated webhook-specific directories under
zerver/webhooks/<webhook_name>/fixtures, where <webhook_name> is
the name of the webhook.
