> The default NN HTTP address is 0.0.0.0. Clients which need to connect to the HTTP address
(e.g. fsck and fetchImage) need an address which is actually resolvable, however. If the configured
NN HTTP address is set to 0.0.0.0, these clients should fall back on using the hostname configured
for the RPC address, with the port configured for the HTTP address.
