This was implemented by containers/netavark #1369; this commit
completes the process by wiring it into Podman. We now respect
the CLI order for configured networks - if a user passes
`--net net1,net2` we guarantee that net1 will be configured
before net2.
For containers created before this patch, we don't retain enough
information to configure networks in CLI order, so we use
alphabetical order instead to still guarantee consistency.
No breaking API changes have been made, but we do add a new
field to supplement the existing map to (optionally) provide
ordering information. The Podman CLI will always pass this.
Existing applications that do not will, again, receive]
deterministic ordering based on an alphabetical sort of network
names.
This requires the latest version of Netavark to work properly.
