Feature: Metadata: Parse out value owner and owner changes

[ghost]

Summary

As a request, a user would like to see the transfer information of a scope (metadata/nft). This means knowing when the value owner or owner values changed on a WriteScopeRequest msg.

Problem Definition

Currently, scopes are shown with all their detail and txs. However, someone looking at a scope would like to see when it changed hands, either as the value owner or the owner.

Proposal

• Create table to hold nft_scope_transfers
• Parse out WriteScopeRequest msgs for the change of value owner or data owner.
• Add API to return that transfer data in a specific format for easy viewing
