Introduce Address type to be used in secondary IPv4 and IPv6 inspect data

structure.

Resolves a discrepancy between the types used in inspect for docker and podman.
This causes a panic when using the docker client against podman when the
secondary IP fields in the `NetworkSettings` inspect field are populated.

Fixes containers#12165
