Azure Endpoint URL is not Trailing-Slash Agnostic

[Jozef833]

Confirm this is an issue with the Python library and not an underlying OpenAI API

• This is an issue with the Python library

Describe the bug

In src/openai/lib/azure.py, there are four cases where the endpoint URL is simply concatenated like:

f"{azure_endpoint}/openai/deployments/{azure_deployment}"
or
f"{azure_endpoint}/openai"

If azure_endpoint has a trailing forward slash (which many comments in the code suggest is allowed, as well as an example in the repository), it will have // in the URL, which is wrong.

To make it agnostic, it should be:

f"{azure_endpoint.rstrip("/")}/openai/deployments/{azure_deployment}"
and
f"{azure_endpoint.rstrip("/")}/openai"

This would be sufficient to fix it: #1893 673a496

To Reproduce

1. Initialize an AsyncAzureOpenAI client.
2. Await on client.chat.completions.with_raw_response.create(**model_args).
3. The error code will be 404 Resource not found because the URL is not properly formatted.
