(cherry picked from commit 022c3a0b)

Since drained nodes could be (partially or fully) broken in iallocator,
we ignore results from these nodes when building the cluster map in
preparation for sending it to the script.

This is a cheap change for the stable branch; ideally we should not
query them at all.

The patch also fixes a typo in iallocator.rst.

Add the following functions to SimpleConfigReader:
GetInstanceByIp, nic ip -> instance name
GetNodePrimaryIp, node name -> node primary ip
GetInstancePrimaryNode, instance name -> primary node

For the first one we precalculate the _ip_to_instance, so we don't have
to loop over all instances for each query.

During a query execution we currently verify whether we have that query
supported in our dispatch table. Since it's an error not to have it
anyway, we move this verification to the class creation, erroring out
early if such a problem exists.

We'll start with a simple ping query, which returns ok if it gets no
query argument, and an error if it gets any. Also non-implemented query
are handled by the base ConfdQuery class, so we don't have to
special-case them in ConfdProcessor anymore.
