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.

platforms
A Go package for formatting, normalizing and matching container platforms.
This package is based on the Open Containers Image Spec definition of a platform.
Platform Specifier
While the OCI platform specifications provide a tool for components to
specify structured information, user input typically doesn't need the full
context and much can be inferred. To solve this problem, this package introduces
"specifiers". A specifier has the format
<os>|<arch>|<os>/<arch>[/<variant>]. The user can provide either the
operating system or the architecture or both.
An example of a common specifier is linux/amd64. If the host has a default
runtime that matches this, the user can simply provide the component that
matters. For example, if an image provides amd64 and arm64 support, the
operating system, linux can be inferred, so they only have to provide
arm64 or amd64. Similar behavior is implemented for operating systems,
where the architecture may be known but a runtime may support images from
different operating systems.
