remove Ingest-Type dropdown
I think there is no need for the dropdown anymore, because we always provide all methods at the same time.
All of
- externalSFTP
- SFTP
- MQTT
can co-exist and are needed.
- The MQTT credentials are (or soon will be) also used to get the logging/status information so they need to be created in any case
- The (internal) SFTP is needed even if the external SFTP was choosen (to sunc from external to internal)
