podman ps --filter doesn't work like docker's

[cjeanner]

Is this a BUG REPORT or FEATURE REQUEST? (leave only one on its own line)

/kind bug

Description

The docker ps --filter allows to pass a "OR" string in the form of "name=foo|bar". Apparently, podman ps --filter doesn't work like this.

Steps to reproduce the issue:

1. run three containers, one named "bar", one named "foo" and the last one "blah"

2. try to list them using podman ps -aq --filter "name=bar|foo"

Describe the results you received:
It doesn't show any container.

Describe the results you expected:
It should show two containers, "foo" and "bar", for instance:

docker ps -aq --filter "name=foo|bar"

Hi @cjeanner, thanks for opening the issue. It's already being tracked in #3394, so I am closing this one here.
