Thread a `tpt_bind_addrs` param through
`open_piker_runtime()` and `open_pikerd()` so
pikerd's bind addrs can differ from the registry
endpoint (support a dedicated `regd` service).
Simplify `load_trans_eps()` to delegate entirely
to `tractor.discovery.parse_endpoints()`.
Deats,
- `conf.toml`: fix maddr prefixes to proper `/ip4/` and `/unix/`, add
`chart` endpoints section, add commented `regd` example.
- `cli/__init__.py`: replace `parse_maddr` with `parse_endpoints`,
rename `--maddr` -> `--maddrs`, parse `regd` key from eps falling back
to `pikerd` addrs.
- `_actor_runtime.py`: thread `tpt_bind_addrs` through runtime open fns
to `open_root_actor`.
- `ui/cli.py`: activate `network` config parsing for chart CLI, extract
`chart` eps for bind and `regd`/`pikerd` for registry, pass
`tpt_bind_addrs` through runtime config.
