htools: rework the algorithm for ChangeAll mode

I think I've identified the problem with the current ChangeAll
mode. The current algorithm works as follows:

- identify a new primary by choosing the node which gives best score
as new secondary
- failover to it...

gnt-instance info: Return static info if node offline

Before this patch “gnt-instance info” would fail with the error message
“Error checking node $node: Node is marked offline” if the instance's
primary node is marked offline and the user didn't explicitely request...

Ignore offline primary when failing over

When the source node for a failover is marked offline, there's no need
to require the user to specify “--ignore-consistency”.

To make it work at all, a number of bugs introduced by the merge of
migration and failover are also fixed by this patch....

htools: replace two hardcoded uses of pri+sec nodes

These two cases use explicit uses of primary and secondary nodes with
Instance.allNodes, which means the code is more flexible if the
internal layout of the instance changes.

I've verified that the output of involvedNodes is not required to be...

htools: add more functions for local disk storage

These will be used in Node.hs for proper add/remove instance
code. Furthermore, we restrict the movable status to the right disk
templates only, so that we don't attempt to move the 'wrong' instance
types....

gnt-instance console: Use query instead of opcode

This means opening the console no longer requires the instance lock,
allowing it to be used during long-running operations (e.g. replacing a
disk).
