feat: Add wait_for_healthcheck to DockerContainer

[rhoban13]

Adding a new wait_for_healthcheck to DockerContainer. This is related to #241, though this provides the functionality on DockerContainer not DockerCompose.

This feature enables testcontainers to achieve a similar functionality with docker compose where a service can declare a depends_on: service_healthy.
