Add Environment Variables From Kubernetes Downward API

[mbillow]

Use the Kubernetes downward API to expose useful runtime information to the Vault Agent container through environment variables.

This PR adds the following environment variables:

• NAMESPACE (technically, this duplicates feature: Add NAMESPACE (from downward API) to list of environment vars #164, but with working tests)
• HOST_IP
• POD_IP

Haha sorry 😂 I thought I was commenting on a vault-helm issue for some reason. I'll get something penned in for the next sprint.
