Bundle rebind transformers with blueprints
Add means for blueprints to register persistence state transformers,
applied on rebind. This will shift the responsibility of creating the
transforms from the Brooklyn operators to the blueprints developers.
Very useful when managing brooklyn of brooklyns or lots of instances
(transparent for the upgrade effector). Works with partial rebind which allows
upgrading of entities needing state transforms without restarting the instance.
As a next step I would like to be able to declare the version of the
blueprint for which a transform is written, so it is executed only against
those versions. I still don't see how to introduce versions in the blueprint
classes though - probably best is to link them to the bundle version, needs
further investigation.
I've been working on the changes now and then for some time, so there are
merge conflicts now, needs rebasing against master.

Move catalog rebind before loading the manifest
Prepare for applying transforms before generating the manifest - need
catalog bundles to load transforms.
