Fix node name and port in diagnostic_remote_logging README

[christophfroehlich]

There are some issues in the README, it took me some time to set everything up (in the end it worked fine!)

• the node name is different, resulting in the parameter yaml not being used
• yaml syntax forbids keys without values
• the telegraf input listener needs a different port if the influxdb still uses the default 8086

@dwffls can you please look into this

@christophfroehlich I'm unsure why your node name differs from what's expected. According to this line in the CMakeLists.txt, the executable name, and therefore the node name, should be influx.

It's possible that you're naming it differently in your launch file. Could you check this?

The rest of your edits are excellent improvements to the README.md and I'd be happy to merge them, provided the node name is changed back to influx.
