chore: make targets for adding metadata (DSP-1289)

Resolves DSP-1289

Thanks @BalduinLandolt, I add my 2 Rappens here instead MD channel.

I think stack-down-delete-volumes is obsolete, because init-db-test is covering it.

I would also not include into make metadata command others than these related to metadata, because most of the time at least init-db-test would be obsolete here too. IMO into make metadata I would include just make stack-up and all possible dataset to be loaded.

@mpro7 thanks for your input!

Sadly, we can only ever have one metadata set at once, since I'm loading them into the same project, otherwise they would just overwrite one another.
But yes, I'll change it right away.

[mpro7]

This is it, thanks!

@mpro7 I moved the metadata stuff to a separate stack-up-with-metadata target. @subotic did not want me to clutter stack-up even more. Does this still seem useful to you?

[mpro7]

Yes, that makes sense.

@BalduinLandolt I have changed the targets a bit. Could you please take a quick look and try it out?
