Create a simulation mode that returns sample data instead of real data, for accounts and transactions

[jeriko]

Why

The repo allows working with the Investec API, but it's hard to build and test against a live API. There is a very hacky simulation endpoint in routes/fake_bank.js, but it's not consistent with Investec's API and doesn't have much functionality. It would be very useful to be able to talk to the same endpoints and just change a request header to use "sandbox" or "live" mode. Probably the easiest way to do this is to decide based on API credentials in the headers.

Definition of Done

Consumers of this repo's API can change their auth credentials to "SANDBOX" and use the same API endpoints to access a sandbox version of the API without needing to change endpoints. For starters, this should work for fetching a list of accounts and a list of transactions.

What

Solving this needs some architectural thinking, and we should chat about it.

Here's a guess at one way to achieve it:

• Create a module that replicates sandbox functionality for getting accounts and transaction records. Devin Pearson has already done some work here, so it may be as simple as pulling in that code.
• Update modules/investec.js to decide whether to send API requests to the openapi.investec.com endpoint or to run an internal simulator function instead
