I think it'd be great if we parsed the env var during the startup phase only (and use the opportunity to error out if something unsupported is passed in). The logic processing the parameters (i.e., this function) can then work off of more strongly typed data (say, a typed string with two constant values).

I'd omit the usage from this example since it's not strictly needed when running locally.

Why do we have curly braces here? It almost looks like JSON but we don't require JSON, do we?
Can we rephrase this in a more user friendly manner, e.g., say one of "ipv4", "ipv6", or a comma-separated list of multiple IP address families?

This PR adds a new env
DO_IP_ADDR_FAMILIESto configure IP families required to add IP addresses in node's status.This also populates the nodes address in the same order as
DO_IP_ADDR_FAMILIESis configured.This fixes the issue #555
