Creating a CrateDB Cloud import job programmatically

## About

Hi. Thanks a stack for conceiving this. I was thinking [job_creator.py](https://github.com/simonprickett/mongodb-hotel-jobs/blob/main/job_creator.py) would already be about creating an import job on CrateDB Cloud, but after looking inside, I learned it is the data provisioning program for MongoDB instead.

So, back to "How to create a CrateDB Cloud import job programmatically?": Over here, there is a patch that will bring a nice SDK and CLI to the table. I think I already mentioned it elsewhere.

- https://github.com/crate/cratedb-toolkit/pull/81

It will enable you to elegantly create a CrateDB Cloud import job by wrapping it into the universal `ctk load` CLI interface to the [CTK table loader subsystem](https://cratedb-toolkit.readthedocs.io/io/), but of course you can do the same in probably 3-5 lines of code when using its Python API.

## Q & A

Is this something you would consider viable and good to have for your tutorial here? Because the patch is ~90% ready, it would not take so many efforts to wrap it up, so I could use this as a good chance to finally do it.

Start by reading job_creator.py and the referenced CTK table loader documentation, then inspect crate/cratedb-toolkit PR #81. Determine how the tutorial should demonstrate creating a CrateDB Cloud import job through ctk load or the Python API, and consider the work done when that flow is integrated into this demo.
