Add go template shell completion for --format
The --format flags accepts go template strings. I use this often but I consistently forget the field names. This commit adds a way to provide shell completion for the --format flag. It works by automatically receiving the field names with the reflect package from the given struct. This requires almost no maintenance since this ensures that we always use the correct field names. This also works for nested structs. ``` $ podman ps --format "{{.P" {{.Pid}} {{.PIDNS}} {{.Pod}} {{.PodName}} {{.Ports}} ``` NOTE: This only works when you use quotes otherwise the shell does not provide completions. Also this does not work for fish at the moment. Signed-off-by: Paul Holzinger <paul.holzinger@web.de>
