It seems that 'explicitely' is wrong, and that the right form is
'explicitly'. This is just fixing the typo plus adjusting affected
paragraphs.

The HTTP server design doc will refer to the LUXI protocol,
so conflicts need to be avoided.

This allows “gnt-node list” to show the difference between modes marked
offline and nodes with e.g. RPC errors (“(nodata)”). node1 is the
master, node2's node daemon crashed and node3 is marked offline:

$ gnt-node list -o name,offline,dtotal,dfree
Node              Offline    DTotal     DFree
node1.example.com N            1.3T      1.3T
node2.example.com N        (nodata)  (nodata)
node3.example.com Y       (offline) (offline)

“kind” is already used in the field definition. “what” seems to
be a better fit for the calls (“what should be queried?”).

While starting to implement this, I found a number of deficiencies:

- Drop regular expressions. As it turned out, only very few fields for
  instances used them, all of which can easily be turned into static
  field names.
- Use two separate calls with a request and response description each.
- Add forgotten list of fields to query request.
- Add value status for case where a field is not available for an item,
  e.g. NIC 3 for an instance with only one network interface.
- Add "timestamp" field type.
- Updated examples.
