From 073f76c1327d296360caa04ef7d751dd00ef5a53 Mon Sep 17 00:00:00 2001
From: Daniel J Walsh <dwalsh@redhat.com>

Subject: Switch podman stop/kill/wait handlers to use abi

Change API Handlers to use the same functions that the
local podman uses.

At the same time:

 implement remote API for --all and --ignore flags for podman stop
 implement remote API for --all flags for podman stop
