1.5.1

Changed

• Changed the default registry to docker.io.
  When the server is not entered as part of the image reference, the sarus run command first looks under docker.io repositories and, if the image is not available, falls back to images under the previous default server (index.docker.io). This is done to preserve compatibility with existing workflows.
  The sarus images and sarus rmi commands treat images from index.docker.io as images from a 3rd party registry.
• If the image manifest obtained from a registry during a pull does not feature the mediaType property, Sarus now attempts to process the manifest as an OCI Manifest V1 instead of failing with an error.
• Updated recommended libnvidia-container version to 1.10.0
• Updated recommended NVIDIA Container Toolkit version to 1.10.0
• Replaced Travis public CICD with Github Actions

Fixed

• Fixed an issue in the generation of manifest digests, where the digest result was incorrectly influenced by JSON formatting
• Fixed an inconsistency with Skopeo which was preventing to pull private images from Docker Hub
