Release all node locks during disk replace

This patch extends commit 7ea7bcf by releasing all node locks in disk
replace for the early release mode. The rationale behind this is:

- LUCreateInstance already releases all node locks while waiting for
  disk synchronization, and does an instance startup later
- WaitForSync only runs (for disk template 'drbd') 'lvs' and read

run in parallel on it, while being a primary for disk storage. Based on

Fix dumpers/loaders after __slots__ cleanup

Commit 154b958 changed (correctly) the __slots__ usage, but this broke
dumpers/loaders since we relied directly on the own class __slots__
field.

To compensate, we introduce a simple function for computing the slots
across all parent classes (if any), and use this instead of __slots__
directly.

Note: the _all_slots() function is duplicated between objects.py and
opcodes.py, but the only other options is to introduce a lang.py for
such very basic language items.

Iustin Pop [Tue, 9 Feb 2010 08:57:50 +0000 (09:57 +0100)]
Add an early release lock/storage for disk replace

This patch adds an early_release parameter in the OpReplaceDisks and
OpEvacuateNode opcodes, allowing earlier release of storage and more
importantly of internal Ganeti locks.

The behaviour of the early release is that any locks and storage on all
secondary nodes are released early. This is valid for change secondary
(where we remove the storage on the old secondary, and release the locks
on the old and new secondary) and replace on secondary (where we remove
the old storage and release the lock on the secondary node.

Using this, on a three node setup:

- instance1 on nodes A:B
- instance2 on nodes C:B

It is possible to run in parallel a replace-disks -s (on secondary) for
instances 1 and 2.

Replace on primary will remove the storage, but not the locks, as we use
the primary node later in the LU to check consistency.

It is debatable whether to also remove the locks on the primary node,
and thus making replace-disks keep zero locks during the sync. While
this would allow greatly enhanced parallelism, let's first see how
removal of secondary locks works.

Ensure all int/float conversions are handled right

int()/float() can raise either ValueError (in case of int("a")), or
TypeError (in case of int(None)). We had many bugs over time due to
this, and a recent one was just diagnosed, so we go over the codebase
