HTTP Poller event source
This event source makes periodic HTTP requests (acting as an HTTP client) to an external HTTP service, and turns the responses into events.
tmctl create source httppoller --eventType <type> --method GET --endpoint https://example.com --interval 20s

- Name: all TriggerMesh components need a unique name per namespace.
- Broker: request converted into CloudEvents will be sent to this location.
- EventType: string that identifies the purpose for all CloudEvent messages produced from this source.
- EventSource: (optional) string that identifies the origin for all CloudEvent messages produced from this source.
- Enpoint: URL location for the remote service to be polled.
- Method: HTTP method.
- Interval: interval between requests formatted as Go duration.
- CA Certificate: (optional) CA certificate configured for TLS connection as plain text.

CA Certificate it should be copied into the text area in plain text.
Events produced have the following attributes:
event-typeis set to the source's provided value.

idis set to a generated UID.
dateis timestamped when generating the CloudEvent at TriggerMesh.
Request response body is used to fill the event payload.
See the Kubernetes object reference for more details.
