Setup app hydrate context and hooks

[mmislam101]

The app will need a few global states and actions that we need to reproduce using react context and hooks:

• Being able to display and hide a full screen loading from anywhere in the app
• On app start, a hydrate flow that for many apps could be many asynchronous actions that need to occur before the main screen can be displayed. Usually with redux/saga, there's a hydrate action and a saga that forks to other actions.
• Promises

Per comments on: https://github.com/ihsan-project/ihsan-react/pull/17 Try to use: https://codeburst.io/beginner-guide-to-react-context-api-with-hook-usestate-4df7c3e08ad to switch from using useReducer instead to individual contexts and wrap the high level component for that context provider only
