Please add Zoom Webhook API (contact transport method) functionality

When adding a contact for alerting, the webhook API doesn't work for Zoom.

Can you guys create a separate transport mechanism for this?

It works similar to Slack, except that it has the authorization token in a header instead of in the URL.

Example:

curl 'https://inbots.zoom.us/incoming/hook/e7aCgmWEZNvrwHxoFWEM1OEZ?format=fields' -X POST -H 'Authorization: BLl5_Mz4vNp677GvwxCSC-MM' -H 'Content-Type: application/json' -d '{"foo":"bar","baz":"qux"}'
