…nput from Model to Deployment (microsoft#1368)

### Motivation and Context

There are different sets of parameters when using OpenAI vs Azure OpenAI

#### OpenAI

1. OpenAI Key
1. Model (`text-davinci-003`)

#### Azure OpenAI
You can deploy multiple versions of the same model (`gpt-3.5-turbo`)
with different resource throughput. This is why "model" is not unique
enough. Instead of Model you specify Deployment and Endpoint

1. OpenAI Key
1. Deployment
1. Endpoint

The `samples\apps\chat-summary-webapp-react` it was using Model term
which may be misleading
