feat(NODE-1477): Configuration revamp (IC-OS integration)

[andrewbattat]

The IC-OS tool has been created, but not yet used by the IC-OS: https://github.com/dfinity/ic/pull/1539

This PR integrates the config tool into the IC-OS. The config tool is utilized for config sanitization, organization, access, and propagation (note that some propagation and access is still done in bash scripts).

Once we are happy with the new design, we will worry about the rollout and preserving backwards compatibility.
