Enhance server capabilities for miniwallet and sms callbacks

[johnwhitton]

This PR is to work on functionality documented in #5

TODO

• Initialize and Instantiate mini-wallet
  • Manually deploy contracts using 001_deploy_assetManager.ts
    • Alternate approach is to Initialize contracts similar to one-wallet blockchain.js
    • Review deploy strategy in MiniWallet Smart Contracts Testing and Deployment #3 including hardhat support for harmony
  • Instantiate AssetManager.sol

Notes
Start of with just using an environment variable for Contract Address
Owners (not Operators) should be deploying AssetManager.sol
Enhance: deploy_AssetManager to save address and hash to a file (can be used by relayer, client and demo for instantiation)
Existing one-wallet deploy logic should be enhance to call getCode to ensure the contract is deployed (mainly for eth-ganache)
Change all GANACHE reference to loclanet

• Develop User API's

  • Develop User API's for Deposit, withdraw and approve (using Request functionality)
  • Document the API's in Postman
  • Create a swagger ui for Local and testnet use

• Add User Functionality to Client

  • Update the Client to include deposit, withdraw and approve functionality

• Create Operator API's (transfer and pay)

• Create Creator API's (transferRequest and billingRequest) should support multiple requests in one call

• Creator Functionality

  • Integrate Creators (transfer and pay) functionality with SMS
  • Creator calls the creator (transferRequest and billingRequest) API's
  • Operator sends SMS to user to approve the transfer or payment
  • User approves via SMS which triggers a twilio webhook for the operator to execute the pay or transfer API

• Additional development tasks

  • Configure the Twilio webhook to call the Creator API's
  • Deploy Testnet version with webhook functionality

• Acceptance Criteria

  • All API's are documented (e.g. Postman)
  • Swagger Client running in Testnet
  • docs.modulo.com is updated
  • Complete end to end tests are written
  • End to End testing (client, server, miniwallet) of all user functions
  • API Testing (server, miniwallet) for all Operator Functions
  • API Testing (server miniwallet) for all Creator Functions

It's insecure to rely on automatically managed contracts in deployment. We need set up our own proxy, understand the exact code within, and manage our own record and step-by-step calls during the use of proxy and follow-up contract upgrades.

There also should not be "User APIs". See comments in #5

I am not following Operator API or Creator API. I need more details to understand the "Creator Functionality". I am not sure whether it is needed. The documented flow in the Wiki envisions all setup performed at the client side. There should not be any (REST) API.

The current client and server do not support network switch so I don't think we need to concern testnet at this time

Can #7 be merged in with this? Alternatively can the mini-wallet functionalities be removed from this PR?

[johnwhitton]

Closing this as work was completed under
#7 which created a separate miniserver and removed swagger
#8 which renamed AssetManager to MiniWallet and updated Approve functionality to allow payments
