[FEATURE] ns exec array fields

[Grifs]

Feature summary

Add the option to have array values in ns exec.

Feature description

It would allow for adding returing e.g. component arguments, docker image id, dependencies, ...

TBD if we should only flatten the array(s), or only allow to concatenate the array into a string (configurable delimiter?, how would the DSL look like?)

Why is this feature beneficial?

Assist helper tools not having to replicate implementation details

A few possible values that would be great to get implemented (without yet making a judgement on how difficult it is to do so):

• arguments
• dependencies
• recursive dependencies
• docker image names of the component
• docker image names of the component & dependencies (maybe always recursive at this point?)
• test docker image name?
• resources
• test resources
