EIDF Documentation Pull Request

Description

Using this example k8s files provided in the tutorial I had to add the "eidf/user" label to get it to submit. This might be because I was running under the eidf018 project, so maybe it has some additional things that are needed, but in case it's a more general requirement, here's an updated version of the training.

This is not a universal label and is addressed in the FAQ for the service under:

My job is rejected due to the following error: "The metadata label 'eidf/user' is missing or has an empty value set."

Might be sensible to add a note to the L1 training page to point to FAQ. Just for users like me who think the provided examples should work and shouldn't require me to read and FAQ.
