Create definition for SystemInfo response

The `/info` endpoint was badly documented, missing various
fields and incorrectly describing others.

This patch defines a type for the endpoint, based on the
API types in the source.

Also removing the response example in favor of
per-field examples, as this prevents an incorrectly
formatted response from masking omissions in the
actual type.
