* feat(repository): apply retention policies server-side This allows append-only snapshots where the client can never delete arbitrary manifests and policies are maintained on the server. The client only needs permissions to create snapshots in a given, which automatically gives them permission to invoke the server-side method for their own snapshots only. * Update cli/command_acl_add.go Co-authored-by: Guillaume <Gui13@users.noreply.github.com> * Update internal/server/api_manifest.go Co-authored-by: Guillaume <Gui13@users.noreply.github.com> * Update internal/server/api_manifest.go Co-authored-by: Guillaume <Gui13@users.noreply.github.com> * Update internal/server/grpc_session.go Co-authored-by: Guillaume <Gui13@users.noreply.github.com> --------- Co-authored-by: Guillaume <Gui13@users.noreply.github.com>
