feat: Adding combined fleet and apm-server container

This modifies the fleet-server-policy so that the agent-policy-apm-server
policy and separate agent is no longer needed. The agent is launched by
the docker-compose.yml too.

The elasticsearch license has been changed from trial to basic so that the
deployment won't age out.
