Add AgentOps Integration to LiteLLM (#9685)

* feat(sidebars): add new item for agentops integration in Logging & Observability category

* Update agentops_integration.md to enhance title formatting and remove redundant section

* Enhance AgentOps integration in documentation and codebase by removing LiteLLMCallbackHandler references, adding environment variable configurations, and updating logging initialization for AgentOps support.

* Update AgentOps integration documentation to include instructions for obtaining API keys and clarify environment variable setup.

* Add unit tests for AgentOps integration and improve error handling in token fetching

* Add unit tests for AgentOps configuration and token fetching functionality

* Corrected agentops test directory

* Linting fix

* chore: add OpenTelemetry dependencies to pyproject.toml

* chore: update OpenTelemetry dependencies and add new packages in pyproject.toml and poetry.lock
