* fix: Correct flatten function in layers
- Added a test.
- Cache current image, track deletes in `whiteouts` as well as normal adds in `layers`.

Delete it when crerating a new snapshot.
- Slight cleanup in `snapshot.go`.
- Format ugly `WalkFS` function.
* fix: Add symbolic link changes to Hasher and CacheHasher
* fix: Better log messages
* fix(ci): Integration tests
* fix(ci): Add `--no-cache` to docker builds
* fix(ci): Pass credentials for error integration test
* np: Missing .gitignore in `hack`
* np: Capitalize every log message

To allow contributors to run the integration tests with their own GCS
buckets and image repos (since not all contributors will have accesss to
the projects used by the kaniko maintainers) this updates the
integration tests so that these can be provided on the command line.
This allows tests to be run individually, without using `make
integration-test`. Previously, part of the test setup was done
in the shell script (creating the context tarball that is required
for the tests that build images with context). Instead it will be
done in the test iself, so we can use `go test` to run tests
individually if we want to.
If we are running only one individual test, we don't want to build
all of the images, so this commit creates a builder which tracks which
images it has built and can be used by a tests to check if it should
build an image before running, or it will use the images that have
already been built by a previous test.
The name of the context tarball has also been made unique (it includes
the unix timestamp) to avoid potential test flakes if two tests using
the same GCS bucket run simultaneously.
