Integrate Watchtower logging into swarms

Related to #702

Integrate Watchtower for optional logging to AWS CloudWatch Logs.

* **Watchtower Integration:**
  - Import `watchtower` in `swarms/utils/loguru_logger.py`.
  - Add `initialize_watchtower_logger` function to configure Watchtower logging.
  - Update `initialize_logger` to optionally use Watchtower logging if configured.

* **Agent Logging Updates:**
  - Import `initialize_watchtower_logger` in `swarms/agents/ape_agent.py`, `swarms/agents/tool_agent.py`, and `swarms/structs/agent.py`.
  - Update logger initialization in `swarms/agents/ape_agent.py` and `swarms/agents/tool_agent.py` to use `initialize_watchtower_logger`.

* **Terraform Configuration:**
  - Add `terraform/logging.tf` to create log groups and policies for AWS CloudWatch Logs.
