[BUG] Infinite regkey updating - Creating WireServerAddressRegValue

[PepijnGramberg]

Describe the bug
While trying to find the cause of some other issue we found some suspicious events in the eventviewer. It is spammed full with just 2 events, that just keep repeating and not really doing anything as each pair is identical. If this is not a bug can someone explain why this is happening and for what this regkey is being used? No documentation about it could be found.

Area/Component:
EventViewer/ServiceFabricNodeBootstrapAgent

Observed behavior:
about 5 times per minute! the following 2 events are being generated. (on each machine)
