As a CNB user on Knative, I can use a PVC to cache builds

[ameyer-pivotal]

Acceptance Criteria Case 1 When I configure a CNB build template for knative that uses a persistent volume claim as an interbuild cache And The build complete successfully Then The cache from that build is available to the next build that uses the same PVC

Case 2 When I configure a CNB build template for knative that uses a persistent volume claim as an interbuild cache And The build fails or is otherwise interrupted at any point Then The cache from that build is not available to the next build that uses the same PVC.

NOTES

• Update this repo with template and example for now. Make a note to create a PR to https://github.com/knative/build-templates after the next Lifecycle release
