[PatchSet] Reworking the index CI to make it more modular.

[mohammedzee1000]

We need to re-write the index ci to make it more modular and easy to use.
Doing so will allow to

1. Call validations individually from anywhere in the code.
2. Provide a list of validators to the index ci engine, which allows for plugging and unplugging of validations.
3. Reduction of index ci code base by atleast half.
4. Makes it easier to write test cases for index ci.

To achieve this, the following tasks need to be completed.

• Writing the basic framework of the index ci, including core component classes and helper functions.
• Writing checks for schema validation of index ci.
• Writing checks for value validation of the index ci.
• Writing CI for the new index CI
• Rewire the index CI.
• Remove old Index CI.
• Discuss possibility of wiring index ci into the pipeline itself.
