Job status cache with Redis

Now that we've introduced Redis and the Redis client for Go, let's quickly add the feature of job status to our previously designed asynchronous API. We need to make the following changes to that project:

We'll create a new project for this feature. It has a similar structure to longRunningTaskV1, which we created previously. The code and files are the same. You can clone the project and rename it longRunningTaskV2.

Let's take a look at the implementation, which includes dependency installs and modifications ...
