Add status output to show the command execution result

[FeynmanZhou]

What is the version of your ORAS CLI

v1.2.0

What would you like to be added?

Suggest adding a standard status output at the end of all oras CLI output to show the final execution result.

It will be much more straightforward for users to understand which resource has been manipulated by ORAS and where it is.

For example, for oras manifest index create:

• Current output

Fetching  v1-linux-amd64
Fetched   v1-linux-amd64
Fetching  v1-linux-arm64
Fetched   v1-linux-arm64
Packed    edb5bc1f0b5c application/vnd.oci.image.index.v1+json
Pushed    [oci-layout] layout-dir:v1
Digest: sha256:edb5bc1f0b5c21e9321b34e50c92beae739250fb88409056e8719d9759f6b5b4

• Expected output:

$ oras manifest index create --oci-layout layout-dir:v1 v1-linux-amd64 v1-linux-arm64 --annotation "platform=multi-arch" 

Fetching  v1-linux-amd64
Fetched   v1-linux-amd64
Fetching  v1-linux-arm64
Fetched   v1-linux-arm64
Packed    edb5bc1f0b5c application/vnd.oci.image.index.v1+json
Pushed    [oci-layout] layout-dir:v1
Digest: sha256:edb5bc1f0b5c21e9321b34e50c92beae739250fb88409056e8719d9759f6b5b

Why is this needed for ORAS?

Improve usability of ORAS output, make the information much more intuitive to users.

Other client tools like docker has the similar status output to show command execution result.
