Add docker-compose resources configuration

[Mario Nevado]

Related to okteto/okteto#3383

We are supporting both resources configuration but just showing one of them in the docs.
We should at to:

resources:
    limits:
      cpu: "2"
      memory: "5Gi"
    requests:
      cpu: 11m
      memory: 60Mi

The docker-compose config:

deploy: 
      resources:
          limits:
            cpus: "2"
            memory: "5Gi"
          reservations:
            cpus: 11m
            memory: 60Mi
