Stream configuration

Define dynamic webhooks for this stream as query parameters.

The general structure is "webhook[.RESOURCE[.STATE]]=http://my_domain/path".

For example:

• define a webhook for stream completion: "webhook.stream.completed=http://my_domain/success"

• define a webhook for all stream events: "webhook.stream=http://my_domain/stream_event"

• define the same webhook for stream completion and failure: "webhook.stream.completed=http://my_domain/path&webhook.stream.failed=http://my_domain/path"

• define a webhook for all events: "webhook=http://my_domain/path"
