Updates #409
Adds a "generic" container workflow. Users build the container in the user workflow and call the reusable container workflow which generates provenance using
cosign attestand uploads it to the container registry.cosign attestuploads additional metadata to the registry which is used during the verification process bycosign verify-attestation. The generic workflow cannot support uploading this additional metadata because our generic workflow is not container aware and users cannot upload the attestation produced by the workflow withcosign attach attestationbecause it does not upload it.This PR adds a new workflow that is container aware. Users build and push their image to a registry. This workflow will use the generic generator to produce a SLSA predicate and then run the
