query2: Add new field status “offline”

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...

Fix N+1 error message

The error contained a typo and is slightly cumbersome. It changes from:

Expose OpSetGroupParams in RAPI and RAPI client

This creates the /2/groups/<name>/modify resource; at the moment, only the

Add the "alloc_policy" attribute to node groups

This can be set at group creation time and via OpSetGroupParams. The default
is "preferred", and existing node groups from previous Ganeti version will
get the attribute set to this value.

Rename “kind” to “what” for calls in query2 design

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

Script to gracefully power off KVM instances

When a node is running KVM instances and that node is rebooted or
shutdown, the gnt-noded daemon is finished and leaves the KVM instances
running. Latter on in the shutdown process, all remaining processes
receive SIGTERM as usual, meaning that the KVM instances are all...

Group operations: CLI code for add/remove/rename a group

Also, minor update to the 2.3 design doc, which was indicating the remove

being consistent with gnt-node and gnt-instance)....
