This fixes the data-race in the config. Depends on: ipfs/go-ipfs-config#16. This does not fix #4942 as there's still a logical race: parallel config updates clobber each other. However, we'll still need the Clone function for the new `--dry-run` flag introduced in #5455. License: MIT Signed-off-by: Steven Allen <steven@stebalien.com>

The user must call this before modifying the config. Given that the config contains slices/maps modifications can modified *shared* state, even after dereferencing.
