podmanV2: implement pull

Implement pulling images for the v2 client.  What I _really_ don't like
is the fact that we are now having a near identical code clone among
`pkg/domain/infra/abi` and `pkg/api/handlers/libpod`.  Partly because we
don't yet have a higher-level pull function and partly because we have
redudancy among `pkg/domain` and `pkg/api`.  Pull might be a high
outlier but I am concerned already by the potential of introducing more
redundancy.  I'd love to `infra/abi` and `pkg/abi` to really use the
same code in the future.
