Add a few more examples

[sylvinus]

We have the web crawler which is nice, but we could add some more. Features that would be good to demonstrate:

• raw queues
• scheduled tasks
• agent with autoscaling

Use the common Dockerfile to run them

I think this is a wonderful idea especially if mrq has some examples of use cases for the 4 different type of raw queues(_raw,_set,_sorted_set, and _timed_set).Will try to work on some examples soon, and possibly looking at writing a blog post for some simple and complex examples for use-case scenario of raw queues.
