Refactor Angaza Connector
The Angaza Connector can be refactored and cleaned up. We can collect ideas for refactoring in this ticket as a follow up.
- generate our SHS db fields from columns in datatable
- move source helper methods into angaza adapter.
- attribute_mapping replacement: just create the mapping of new columns and values and put it directly onto item as like item\["mapped_attributes"\] and then delete the complete attribute_values part
- refactor this to not shadow the method: `offset = { clients: page * 100, payments: page * 100, accounts: page * 100 }`
- refactor this to not need instance var: `@next_page = fetch(offset).first`
