[Enhancement] Add authentication to docker copy just like in gradle check

[peterzhuamazon]

We reach the limit of docker pull when running docker copy from docker hub to ecr due to over the limit without authentication:

Error: GET https://index.docker.io/v2/opensearchstaging/ci-runner/manifests/ci-runner-ubuntu2004-opensearch-build-v2.1: TOOMANYREQUESTS: You have reached your pull rate limit. You may increase the limit by authenticating and upgrading: https://www.docker.com/increase-rate-limit

https://build.ci.opensearch.org/job/docker-copy/618/console

Thanks.

The problem appears that we need to login to multiple registries as we need to pull with one credential and push with the other credential.

[Triage] This requires both the source and target to auth with docker so that both pull and push can happen with authenticated users to avoid rate limit.
