Azure OpenAI: prepare for 1.0 (#132)

## Issue
This is a part of langchain4j/langchain4j#3155

## Change
Removed `AzureOpenAiTokenCountEstimator` bean auto-configured by
default. Please configure it yourself and explicitly specify the model
name.

## General checklist
- [ ] There are no breaking changes
- [ ] I have added unit and/or integration tests for my change
- [ ] The tests cover both positive and negative cases
- [X] I have manually run all the unit and integration tests in the
module I have added/changed, and they are all green
- [ ] I have added/updated the
[documentation](https://github.com/langchain4j/langchain4j/tree/main/docs/docs)
- [ ] I have added an example in the [examples
repo](https://github.com/langchain4j/langchain4j-examples) (only for
"big" features)
