Implement Google sign-in using clean architecture

[Zaid-0504]

Summary:

In the present code base goggle sign-in is directly implemented in Login Activity we can make it better using clean architecture and View Model
Steps to reproduce:

How can we reproduce again the issue?

Expected behavior:

To handle the sign-in function at a separate thread rather than in the main UI thread
Observed behavior:

The Sign-in feature is working on the main UI thread which can compromise user experience if an error occurs

Device and Android version:

What make and model device (e.g., Samsung Galaxy S3) did you encounter this on? What Android
version (e.g., Android 4.0 Ice Cream Sandwich or Android 6.0 Marshmallow) are you running? Is it
the stock
version from the manufacturer or a custom ROM?

Screenshots:

Can be created by pressing the Volume Down and Power Button at the same time on Android 4.0 and higher.
