This patch adds support for Xen's CPU scheduler 'cpu_cap' and
'cpu_weight' parameters.

Ganeti default values (cap: 0=unlimited, weight: 256) are Xen defaults.

cpu_cap is not validated correctly because of actual Ganeti limitation
on checks. I'd need check methods to get beparams or vcpus to get moved
to hvparams.

This patch removes the last HTools module imports from non-htools code
(the HTools.Types module), but it requires an associated cleanup:
using luxi-specific constants for luxi timeouts (the only effect is
that one timeout decreases from 15 to 10, the default value in the
python code), and moving of the (now) RAPI specific constants to
RAPI.hs (which allows simplifying their type/usage).

When initially implementing the node query, I thought the 'powered'

make its query complex.

In reality, it's a simple config query, which we can support

RSUnavail case in many places.

This replicates in the Haskell Query2 implementation the behaviour of
the Python code: if a "simple" filter is passed (one that contains
only Or aggregators  and EQ binary ops on the name field), then an
failure is flagged if the given values are not known.

Our implementation is pretty straightforward, with a few details:

- we ignore any NumericValues passed, since that inconsistency will be
  flagged by the filter compiler
- we return an the non-normalized names from the getRequestedNames
  function, and not the fully-normalized ones; this will be done later
  in individual query functions
- we test a few of the desired behaviours of the above-mentioned
  function
