Create a module/plugin to support deployment with the Ledger Hardware Wallet

Outline

The goal of this task is to create a module/plugin for Embark that supports deploying smart contracts authorizing each of them to deploy with a Ledger Hardware Wallet.

The deployment config in config/contracts.js should be something like:

module.exports = {
  ...
  "develop": {
      "deployment": {
        "accounts": [
          {
            "HardwareWallet": "Ledger"
          }
      ]
    }
  }
}

then, with the Ledger connected, doing embark run should deploy the contracts. Each deployment needs a confirmation from the ledger device".

Important:

Keep in mind that the default environment in contracts.js will be merged with any other environment that’s being used (develop being the default), which connects to the locally installed blockchain by default. It’s required that it doesn’t matter what Embark connects to.

• API: https://github.com/LedgerHQ/ledgerjs
• Provider example which is key: https://github.com/LedgerHQ/ledgerjs/blob/master/packages/create-dapp/template/src/wallets.js

Acceptance Criteria

• It should be created as an isolated Embark module (lib/modules) & All major functionality should be there
• The scenario described above should work for the testnets (e.g kovan) and livenet
