Added sync and async api tests for Agent feature

[BhavaniKondra]

Description

This PR adds test coverage for the Agent feature by implementing both synchronous and asynchronous API tests.

The following areas are covered:

• Agent APIs
• Tools APIs
• Tasks APIs
• Teams APIs
• End-to-end agent execution scenarios

These tests validate that both sync and async execution paths behave consistently and correctly.

How Has This Been Tested?

The following test suites were executed locally to verify the functionality:

• tests/agents/test_3001_tools.py

Both synchronous and asynchronous execution flows were validated.
Logs were verified to ensure successful execution and correct responses from APIs.
