Archivista Backend

[colek42]

Feature request

Archivista is a open source CNCF project under the in-toto organization. It is a attestation store and query service.

Use case

Tekton Chains would implement the Archivista API to store attestations. This would allow Archivista and Witness users to leverage Tekton Chain within their workflows.

[lcarva]

Chains already supports various storage backends. Adding support for Archivista makes sense to me. Relevant code: https://github.com/tektoncd/chains/tree/main/pkg/chains/storage
