Disable tracing in Promptflow by default (#3907)

# Description

Tracing frequently causes problems because OAI/AOAI keeps changing token
statistics contracts. Disabling this feature to prevent these issues.

# All Promptflow Contribution checklist:
- [ ] **The pull request does not introduce [breaking changes].**

license.**
- [ ] **Create an issue and link to the pull request to get dedicated
review from promptflow team. Learn more: [suggested
workflow](../CONTRIBUTING.md#suggested-workflow).**

## General Guidelines and Best Practices
- [ ] Title of the pull request is clear and informative.
- [ ] There are a small number of commits, each of which have an
