Improve ncd status logging

Fixes #12.

In addition, restore the original formatting of ncd status line in `/var/log/ncm-cdispd` to avoid breaking existing parser for this file (I know that line is parsed to raise attention when a component failed).

Still work in progress, would like to add the list of failed components as described in #12.
so what i have is some leftovers i guess. well, if it causes issues, i'll open an issue with `ncm-ncd`.
