CacheCommand returns true if the command should be cached. Currently, it's only true for RUN but can be added to ADD/COPY later on (these are different since the contents of files for ADD/COPY need to be included in the cache key generation). I also changed CreatedBy to String so that we can log each command before cache extraction or regular execution takes place.
