CLI UX Consistency Pruning Volumes

[damaestro]

Issue Description

Inconsistency for the CLI UX which makes documentation harder and muscle memory more expensive. Adding a simple compatibility option would bring the two UX for volume management closer together.

Steps to reproduce the issue

Steps to reproduce the issue

1. docker volume prune -a (and podman volume prune -a

Describe the results you received

jon@dahome:~$ docker volume prune -a
Error: unknown shorthand flag: 'a' in -a
See 'podman volume prune --help'

Describe the results you expected

To maintain a compatible UX for the CLI, we should support -a for the volume prune. The default behaviors between docker and podman are different and we should unify them more.

In Docker CE you need to pass -a to do a proper dangling volume cleanup.
In Podman it does the right thing.

We should add -a as compatibility so both docker volume prune -a and podman volume prune -a work.

This is still valuable to fix.

Potentially a breaking change, but important for Docker compat. Adding a 6.0 label for consideration
