Add AZURE support

[cristianorevil]

This PR add the support for Azure OpenAI Services (Vision & DALLE-3)

Some considerations:

• Azure parameters are managed only in .env file (not in web interface), I have updated the README file with instructions
• On Azure the vision ad dalle-3 distributions must be in the same reource and same region
• If in .env are present OPENAI and AZURE settings, OPENAI has the priority
• The code probably need some refactor (i am not an high level python developer)

My tests with AZURE are ok, please test also OPENAI

@abi Will this be merged in this week? Waiting for using it...

@thuzhf Azure GPT 4 Vision has low token limits per minute so this hasn't been a priority for me. Have you tried cloning cristianorevil:azure-support and using it directly? You don't need to wait for this to be merged in to use it.

Since stream requests are already supported and the issue with token limitations has been somewhat improved, can we support Azure now?
