lazy_find should accept lambda to preprocess value

[miha-plesko]

We're hitting an issue where we have to copy value from Flavor to Vm, but divide it by 2^20 prior saving. Something like:

persister.flavors.build(
  ... 
  :memory => flavor.memory_in_mb.megabytes # store in bytes
)

persister.hardwares.build(
  ...
  :memory_mb => persister.flavors.find(flavor_ref).memory / 1.megabytes  # convert to megabytes
)

Problem is that we currently have to use .find() which may potentially result in ordering issues. Would it be possible to let .lazy_find() accept a block where we could preprocess the value? Something like this would be fantastic:

persister.flavors.lazy_find(flavor_ref) { |flavor| flavor.memory / 1.megabyte }
