Extend the flags of `podman manifest add` to include also:
* cert-dir
* auth-file
* creds
* tls-verify
These options are useful when adding to a manifest an image that is not
part of the local image store. The image resides on a remote registry
that falls into one of these cases: it's not using tls termination, it requires
authentication or it's secured with an unknown tls certificate.
Consider the following scenario: a multi architecture manifest is created as
part of a multi-step CI pipeline running in a containerized way.
All the images referenced by the manifest live inside of a registry
secured with a self-signed tls certificate.
Without this patch the manifest creation step would have to pull all the
multi-architecture images locally via `podman pull`.
With this patch the usage of `podman pull` would not be needed because the
images' digests can be requested straight to the registry. That means the
execution of manifest creation step would be faster and result in less disk
space and network bandwidth being used.
Finally, this is a propagation of a similar fix done inside of buildah
via https://github.com/containers/buildah/pull/2593

* Support the `X-Registry-Auth` http-request header.
* The content of the header is a base64 encoded JSON payload which can
either be a single auth config or a map of auth configs (user+pw or
token) with the corresponding registries being the keys. Vanilla
Docker, projectatomic Docker and the bindings are transparantly
supported.
* Add a hidden `--registries-conf` flag. Buildah exposes the same
flag, mostly for testing purposes.
* Do all credential parsing in the client (i.e., `cmd/podman`) pass
the username and password in the backend instead of unparsed
credentials.
* Add a `pkg/auth` which handles most of the heavy lifting.
* Go through the authentication-handling code of most commands, bindings
and endpoints. Migrate them to the new code and fix issues as seen.
A final evaluation and more tests is still required *after* this
change.
* The manifest-push endpoint is missing certain parameters and should
use the ABI function instead. Adding auth-support isn't really
possible without these parts working.
* The container commands and endpoints (i.e., create and run) have not
been changed yet. The APIs don't yet account for the authfile.
* Add authentication tests to `pkg/bindings`.
