This PR adds support for the dockerignore file. Previously when kaniko had support for the dockerignore file, kaniko first went through the build context and deleted files that were meant to be ignored. This resulted in a really bad bug where files in user mounted volumes would be deleted (my bad). This time around, instead of modifying the build context at all, kaniko will check if a file should be excluded when executing ADD/COPY commands. If a file should be excluded (based on the .dockerignore) it won't be copied over from the buildcontext and shouldn't end up in the final image. I also added a .dockerignore file and Dockerfile as an integration test, which should fail if the dockerignore is not being processed correctly or if files aren't being excluded correctly. Also, I removed all the integration testing from the previous version of the dockerignore support.
