[BUG] Can not turn off telemetry and telemetry logs

[aaronjolson]

Describe the bug
I am seeing these telemetry warnings all over my stdout output

%6|123.795|GETSUBSCRIPTIONS|my-chat#producer-2| [thrd:main]: Telemetry client instance id changed from AAAAAAAAAAAAAAAAAAAAAA to asbgahgjksgbjk
WARNING:opentelemetry.attributes:Invalid type NoneType for attribute '__computed__.cumulative_token_count.completion' value. Expected one of ['bool', 'str', 'bytes', 'int', 'float'] or a sequence of those types
WARNING:opentelemetry.attributes:Invalid type NoneType for attribute '__computed__.cumulative_token_count.prompt' value. Expected one of ['bool', 'str', 'bytes', 'int', 'float'] or a sequence of those types
WARNING:opentelemetry.attributes:Invalid type NoneType for attribute 'llm.usage.completion_tokens_details' value. Expected one of ['bool', 'str', 'bytes', 'int', 'float'] or a sequence of those types
WARNING:opentelemetry.attributes:Invalid type NoneType for attribute 'llm.usage.prompt_tokens_details' value. Expected one of ['bool', 'str', 'bytes', 'int', 'float'] or a sequence of those types

I do not want to see these anymore. I have tried running

 > pf config set telemetry.enabled=false
Set config [{'telemetry.enabled': 'false'}] successfully.

but that does not seem to have any effect on run output.
I also tried creating a pf.yaml file in ~./promptflow
The contents of this file looks like

telemetry.enabled=false

How To Reproduce the bug
Steps to reproduce the behavior, how frequent can you experience the bug:

1. run a command similar to

python -m promptflow._cli._pf.entry flow test --flow/path/to/flow --user-agent "prompt-flow-extension/1.20.2 (darwin; arm64) VSCode/1.95.3"

Expected behavior
I expect none of these logs

%6|123.795|GETSUBSCRIPTIONS|my-chat#producer-2| [thrd:main]: Telemetry client instance id changed from AAAAAAAAAAAAAAAAAAAAAA to asbgahgjksgbjk
WARNING:opentelemetry.attributes:Invalid type NoneType for attribute '__computed__.cumulative_token_count.completion' value. Expected one of ['bool', 'str', 'bytes', 'int', 'float'] or a sequence of those types
WARNING:opentelemetry.attributes:Invalid type NoneType for attribute '__computed__.cumulative_token_count.prompt' value. Expected one of ['bool', 'str', 'bytes', 'int', 'float'] or a sequence of those types
WARNING:opentelemetry.attributes:Invalid type NoneType for attribute 'llm.usage.completion_tokens_details' value. Expected one of ['bool', 'str', 'bytes', 'int', 'float'] or a sequence of those types
WARNING:opentelemetry.attributes:Invalid type NoneType for attribute 'llm.usage.prompt_tokens_details' value. Expected one of ['bool', 'str', 'bytes', 'int', 'float'] or a sequence of those types

to appear in stdout. I do not want these telemetry calls to run.
