Generate ephemeral-storage requests and limits configuration using deploy labels

[jvitor83]

What would you like to be added?

Allow to use labels in the deploy section to convert to kubernetes resources requests and limits for ephemeral-storage.

Example:

services:
  app:
    image: node:18-alpine
    ports:
      - 3000:3000
    deploy:
      labels:
        requests.ephemeral-storage: 1Gi
        limits.ephemeral-storage: 1Gi

Generates:

apiVersion: apps/v1
kind: Deployment
...
spec:
    ...
    spec:
      containers:
        - image: node:18-alpine
          name: app
          ports:
            - containerPort: 3000
              protocol: TCP
          resources:
            limits:
              ephemeral-storage: 1Gi
            requests:
              ephemeral-storage: 1Gi

Why is this needed?

By using the generated yaml files, if those ephemeral-storage resources configuration didn't exists and if the cluster where the deploy will happen are on low ephemeral storage, this gives an error.
By have the possibility to put those config, we can properly set how much reserve should have.
