Upload image tar to release assets as part of pipeline

[orenbm]

We would like to have a tar of the relevant docker image in the github release page. We have it for this release. In this case, we did it manually by running locally:

docker pull cyberark/conjur-authn-k8s-client:0.18.1
docker save -o conjur-authn-k8s-client-0.18.1.tar cyberark/conjur-authn-k8s-client:0.18.1

and manually uploading the tar to the release page.

We would like this to happen automatically once we push a new tag and release it. This can be done by running the steps above in the Jenkins pipeline and archiving the artifact. We can also look into this github action to perform this.

DoD:

• image tar is automatically uploaded to release pages
• Process is documented (if needed)
• A list of projects that can do the same process is created
  • PRs are created for those projects to perform the same action

@orenbm why was a tar of the client uploaded to the release of the SP? is that a requirement? Shouldnt the tar be of the Secrets Provider no the client?

it was done by mistake, thanks for seeing this! I removed it from the SP release and will upload it to the authn-client release
