Allow in-place updates for all compatible types

We previously only allowed a resource to update in-place when the 'type'
field in the old and new templates matched. In an age of environment type
mappings, this is incorrect. Instead, allow a resource to be updated
in-place when the old and new resource plugins are of the same class, since
this is actually what determines whether handle_update is capable of
correctly updating the resource in-place.

There is a special-case for TemplateResource as we currently subclass it
for each template type, but all TemplateResource subclasses are in fact
capable of converting between each other via a stack update.
