Implement Algolia Search for searching site contents

[nilandev]

The current search functionality is limited and it is implemented natively using Django. It can be replaced by more intituative Algolia search.

Steps involved:

1. Create an API key with Algolia
2. Implement changes in django models to allow data indexing.
3. Implement Search in the frontend using Algolia recommended javascript.
