Make container names be passed via the ENV

This commit adds two new environment variables
* RESTATE_CONTAINER_IMAGE - defaults to `ghcr.io/restatedev/restate:main`
* SERVICES_CONTAINER_IMAGE - defaults to `localhost/restatedev/test-services:latest`

With that it is possible to chose what runtime to use, and which sdk.
