Enable test recordings for tests\inference, tests\telemetry and tests\connection

[dargilco]

Several changes as a result of getting all my tests pass from recordings on these three API surfaces.

• Reduce the number of environment variables needed for connection tests, until I'm able to set up a more complex AI Studio for proper testing, where I will have multiple AOAI connections and AI Services connections.
• Update dev_requirements.txt with additional dependencies needed to run inference tests
• Remove sanitation of connection names, as those are actively used to verify tests pass/fail in connection tests. I don't think connection name by itself should be consider as a sensitive value that must be removed. But will need to talk to Ankit about it.
• Add sanitizers for api-key and Application Insights connection strings in response from the service
• Do not record chat completions call with AzureOpenAI, because that's a non-Azure SDK and does not support recording. Do the call only when you run live tests without recordings. Use recording base class utility function is_live_and_not_recording() to check recording status.
• Remove tests that call project_client.telemetry.enable(destination="https://some.otlp.collector.endpoint") for now as I need to change them to run live against some local host service (3rd party tool that displays OTEL), and understand how that works.

Not in this PR: I updated the master copy of the .env file, and checked-in the recordings to the azure-sdk-for-python-pr repo.
