Cognitive services nodes have static westus endpoints

[ibmrcruicks]

westus api endpoint will not work with cognitive services instances and API keys issued outside US.

Valid keys from UK Azure Computer Vision subscription are rejected by westus -- need to be select endpoint to match subscription e.g westeurope.api.cognitive.microsoft.com for UK subscription northeurope.api.cognitive.microsoft.com for DE subscription etc please add a select to the config menu for the API endpoint

I would really like this fixed too, since it means we can't use these for prototypes or demos in EU customers due to legal concerns.

another inputfield with users endpoint would be awesome, there is no good alternatives to this
