Shell completion for podman ps and podman pod ps --filter
Add all available filter options for `podman ps` and `podman pod ps` to the completions. Refactor the code a bit to make it easier to handle key value pairs in completions. The `completeKeyValues` function helps to reduce code duplication. Also make use of the new filter logic in the completions. Signed-off-by: Paul Holzinger <paul.holzinger@web.de>
