Feature: Use jetpack navigation component

**Is your feature request related to a problem? Please describe.**

Currently we have a custom implementation for navigation.

**Describe the solution you'd like**

Use jetpack [Navigation component](https://developer.android.com/guide/navigation).
Also initialize the viewmodels from the NavController backstack.

**Additional context**

It is a very well documented library and using it would also reduce bugs due to navigation in our code.
