Fix podman inspect on overlapping/missing objects

This started as a small fix to `podman inspect` where a container
and image, with the same name/tag, were present, and
`podman inspect` was run on that name. `podman inspect` in 1.9
(and `docker inspect`) will give you the container; in v2.0, we
gave the image. This was an easy fix (just reorder how we check
for image/container).

Unfortunately, in the process of testing this fix, I determined
that we regressed in a different area. When you run inspect on
a number of containers, some of which do not exist,
`podman inspect` should return an array of inspect results for
the objects that exist, then print a number of errors, one for
each object that could not be found. We were bailing after the
first error, and not printing output for the containers that
succeeded. (For reference, this applied to images as well). This
required a much more substantial set of changes to properly
handle - signatures for the inspect functions in ContainerEngine
and ImageEngine, plus the implementations of these interfaces,
plus the actual inspect frontend code needed to be adjusted to
use this.

Fixes #6556
