Integrate Pet Clinic AI Agents with Nutrition Service (#159)

*Description of changes:*

- Integrates Pet Clinic AI agents with the existing nutrition service to
provide dietary recommendations based on the clinic's actual product
inventory. Nutrition Agent now queries the nutrition service API for
pet-specific dietary information and product recommendations

- Adds nutrition service to the ingress endpoint and extends the
database with a products column containing Pet Clinic's pet food product
inventory.

- Update `setup-agents-demo` script to auto discover their nutrition
service and/or allow users to provide the link to their nutrition
service's endpoint.

- Removes intentional transient errors from Nutrition Agent 

- Updates `requirements.txt` for both agents to include latest version
of Strands and ADOT.

+   The Nutrition Agent relies on the nutrition service to retrieve pet nutrition information and provide accurate dietary recommendations. To enable this feature, the [EKS demo](#eks-demo) must be set up first. The deployment script will attempt to auto-discover the nutrition service endpoint from your EKS cluster. If auto-discovery fails or you want to specify a custom endpoint, you can manually provide the nutrition service URL using the `--nutrition-service-url` parameter:
