Migrate an object using customized logic to create id in Fedora 4

[awead]

Use Case:
I want to migrate my Fedora 3 objects, but I don't want to use the PID that comes with them.

Examples:

1. Using Fedora's own minting setup
   Given Fedora 3 object namespace:1234
   When I migrate this to Fedora
   I want the Fedora 4 object to be the default UUID minted by the application
   And I want the namespace:1234 pid to be searchable in a predicate on the migrated resource

2. Using some other minting scenario
   Given Fedora 3 object namespace:1234
   When I migrate this to Fedora
   I want the Fedora 4 object to be /some/path/to/resource/12/34/xyz
   And I want the namespace:1234 pid to be searchable in a predicate on the migrated resource
