This commit upgrades the default CNB builder image from
cloudfoundry/cnb:0.0.43-bionic to cloudfoundry/cnb:0.0.53-bionic.
It also adds integration tests for the Maven and Gradle plugins
to verify both versions are supported.

Cloud Native Buildpacks platform API version 0.2 introduced
two breaking changes: the order of invoking the restore and analyze
phases was reversed, and the cache phase was removed in favor of
distributing caching across other phases.

This commit adds support for Cloud Native Buildpacks builders that
implement platform API version 0.2, while maintaining compatibility
with builders that implement Lifecycle version platform API
version 0.1.
