It seems like .dockerignore deletes files containeed within the file locally upon
docker build, so I created a temporary test dir to make sure the
--ignore flag works. We make sure it exists before building docker and
kaniko for Dockerfile_test_ignore, and then delete it after the builds
have completed.
Added a --ignore flag to ignore packages and files in the build context.
This should mimic the .dockerignore file. Before starting the build, we
go through and delete ignored files from the build context.

This change refactors the build loop a bit to make cache optimization easier in the future. Some notable changes:
The special casing around volume snapshots is removed. Every volume is added to the snapshotFiles list for every command that will snapshot anyway.
Snapshot saving was extracted to a sub-function
The decision on whether or not to snapshot was extracted
* Rework cache key generation a bit.
Cache keys are now based on the previous commands, rather than the previous state
of the filesystem.
* Refactor command interface a bit, only cache the context for commands that use it.
I merged a contributor's PR which modifed the HasFilepathPrefix function
to take an additional argument, but the PR hadn't been rebased. One of the
liting tests in Travis caught this bug.
As described in #373, kaniko panics when provided with --cache and --no-push since it tries to infer a cache repo from the destination, which doesn't exist.
To fix this, I added a check to make sure --cache-repo is passed in when both these flags are provided.
