Remove LLMObs logs/metrics references

[Kyle-Verhoog]

What does this PR do?

Remove references to logs and metrics being sent from the clients.

Motivation

It is now recommend using the LLM Observability product directly rather than sending logs and metrics. The logs and metrics code is being removed from the libraries.

Review checklist (to be filled by reviewers)

• Feature or bugfix MUST have appropriate tests (unit, integration, e2e)
• Add the qa/skip-qa label if the PR doesn't need to be tested during QA.
• If you need to backport this PR to another branch, you can add the backport/<branch-name> label to the PR and it will automatically open a backport PR once this one is merged

[Yun-Kim]

Two questions:

1. Should we also remove the integration metrics from each corresponding metadata.csv which lists the provided integration metrics?
2. Looks like the ootb dashboards are reliant on these metrics. Should we remove those from the dashboard as well or convert them to use APM trace metrics instead?

[Kyle-Verhoog]

@Yun-Kim good catch. I'm ok to leave them for now in case people are using them and just remove the documentation to prevent further usage. When we go to do the customer notifs we can set a date to remove the metrics.
