This patch introduces `.dvc/cache/stages` that is used to store previous runs and their results, which could then be reused later when we stumble upon the same command with the same deps and outs. Format of build cache entries is single-line json, which is readable by humans and might also be used for lock files discussed in #1871. Related to #1871 Local part of #1234
