Test using lumispy as endpoint

[jordiferrero]

Test if endpoint:lumispy works.

@jordiferrero is this PR still relevant or could we just close it?

[jordiferrero]

We can close it because I never managed to make that work.
So the Azure tests go though my personal azure endpoint usename instead of the lumispy one.

I think it is OK as Azure is working well.

Yes, if this is working fine and as long as this stays like this, no need to take any actions!
