Retrieve the ingress-address from a relation when available.
Otherwise, return the private-address.
When used on the consuming side of the relation (unit is a remote
unit), the ingress-address is the IP address that this unit needs
to use to reach the provided service on the remote unit.
When used on the providing side of the relation (unit == local_unit()),
the ingress-address is the IP address that is advertised to remote

reach the local provided service on this unit.
Note that charms may document some other method to use in
preference to the ingress_address(), such as an address provided
on a different relation attribute or a service discovery mechanism.
This allows charms to redirect inbound connections to their peers
or different applications such as load balancers.
