To fix this,
atlas.server.ha.enabled will not be shown on the UI and instead derived. But if for whatever reason we need to do some debugging/troubleshooting on Atlas, we may allow the user to override the property.
* single Atlas Server => write config with atlas.server.ha.enabled=false (if atlas.server.ha.enabled is set to true, still write it out as false)
* multiple Atlas Servers => write config with atlas.server.ha.enabled=true (only if atlas.server.ha.enabled is not a property, otherwise, take its value)
