fix: telemetry fixes (inference and core telemetry) (#2733)
# What does this PR do?

I found a few issues while adding new metrics for various APIs:

currently metrics are only propagated in `chat_completion` and
`completion`

since most providers use the `openai_..` routes as the default in
`llama-stack-client inference chat-completion`, metrics are currently
not working as expected.

in order to get them working the following had to be done:

1. get the completion as usual
2. use new `openai_` versions of the metric gathering functions which
use `.usage` from the `OpenAI..` response types to gather the metrics
which are already populated.
3. define a `stream_generator` which counts the tokens and computes the
metrics (only for stream=True)
5. add metrics to response


NOTE: I could not add metrics to `openai_completion` where stream=True
because that ONLY returns an `OpenAICompletion` not an AsyncGenerator
that we can manipulate.


acquire the lock, and add event to the span as the other `_log_...`
methods do

some new output:

`llama-stack-client inference chat-completion --message hi`

and in the client:

/>

these were not previously being recorded nor were they being printed to
the server due to the improper console sink handling
