Feed upload fails if Debug API is not set

[agazso]

This causes a problem when trying to upload gateway nodes (e.g. nodes which does not expose their Debug API).

It seems that it queries the /health and /stamp endpoints at the beginning and to print the stamp status at the end which is not strictly necessary in the case of a gateway. It would be better to detect the availability of these endpoints but not fail if they are not available (effectively make them optional).

Relevant logs:
