chore: make e2e use less resources (envoyproxy#1190)

**Description**

Previously, all the end-to-end tests didn't configure Envoy container's
resource requests. By default, it would use `cpu: 100m` & `memory:
512Mi`, and the more we add tests, the more the memory it would use
hence the tests might get stuck in the middle.
