Here I am adding a config option and geth flag (`--history.chain`) for configuring history pruning. There are two options available: - `--history.chain all` is the default and will keep all history like before. - `--history.chain postmerge` will configure the history cutoff point to the merge block. The option doesn't actually do anything right now, but we need it as a precursor for other history pruning changes.
