Silently retry Fronius inverter endpoint 2 times

[farmio]

Proposed change

Almost 1% of current_inverter_data() (GetInverterRealtimeData.cgi with device scope) requests on Symo devices result in BadStatusError Code: 8 - LNRequestTimeout due to flaky internal communication between Datalogger (our bridge device) and inverter.
Subsequent calls always succeeded in my ~5000 tests - so we retry 2 times silently before raising an error (and writing to the log).
