A merchant's bank connection

GET/api/v1/credit/bank-connections/{bank_connection_id}

Where a started connection stands: pending, completed (with the accounts the merchant shared and the repayment account), failed (with failure_reason) or expired. Poll it from the wizard instead of the event feed if you prefer; when the merchant has finished and Plaid's notice has not reached DayZero, the read asks Plaid. A connection on another business is 404 CREDIT_783.
