Vincent Bernardoff 6d41b3d38c Shell: Improve the CLI of tezos-node
* Use subcommands:
  * `tezos_node run`
  * `tezos_node config`
  * `tezos_node identity`
* Regroup all on-disk data in `--data-dir`
* Split `Node_main` in multiple files.
* Add DNS resolution for `--net-addr` and `--rpc-addr`
* Hardcode `bootstrap.tezos.com` as bootstrap peer(s)
* Add `--no-bootstrap-peers`
* Rename `--expected-connections` -> `--connections`
