Grafeas storage for PipelineRun-level provenance (#601)
Support storing pipelinerun level provenance in grafeas backend. There are 3 main aspects of the PR: - created different BUILD Notes for storing both taskrun and pipelinerun level provenance/occurrence in grafeas that attest the same artifact. - extracted artifact identifiers from intoto subjects instead of calling individual helpers to extract from results. - changed TektonObject "GetKind" method to "GetGVK" to get the whole GroupVersionKind information.
