feat: Add always_enqueue option to bypass URL deduplication

[Rutam21]

Description

This PR implements a new input parameter, always_enqueue, in the Request.from_url constructor. This feature allows users to bypass the request deduplication process, ensuring that each request is always enqueued and processed.

Key Changes:

• Added the always_enqueue parameter to the Request.from_url method.
• When always_enqueue is set to true, a random unique key is generated for each request, preventing it from being considered a duplicate.
• This enhancement provides users with a convenient way to enqueue requests without worrying about deduplication.

With this addition, users can seamlessly manage their requests while maintaining flexibility in their queuing strategy.

Issues

Fixes #547

Testing

The modifications can be verified by making requests to the same URL. The operations should execute each time this is done without treating it as a duplicate request when always_enqueue is set to true.

This looks quite good, but make sure the CI passes (lint check, type check, unit tests... all are failing), see the CONTRIBUTING.md for more information.
