FinanceAgent - enable on Xeon, remote endpoint, and refactor tests

[alexsin368]

Description

• Enable support for running OpenAI models on Xeon
• Enable remote endpoints for the LLMs on the agents only (docsum and dataprep will still run LLM locally)
• Reorganize set_env.sh environment variables
• Refactor tests: since Xeon test steps are similar to Gaudi's, breaking out the tests to make it easier to add new test steps or new tests for hardware
