`drg` example commands seem a bit off

[ctron]

When testing Keycloak changes, I notices that some of the drg example commands from the shell script no longer work:

drg stream example-app
error: Found argument 'example-app' which wasn't expected, or isn't valid in this context

USAGE:
    drg stream [OPTIONS]

For more information try --help

And:

drg cmd set-temp device1 --app example-app --payload '{"target-temp":25}'
Error from drogue cloud: Unexpected error HTTP 406 Not Acceptable

@jbtrystram I didn't check into any details, but maybe you could do one round of testing (shell script and console example) to see they are still up to date.
