Expose HostConfig Resources via ContainerRequest

[nhatthm]

Description

I have a use case where I need to set the ulimits for a container

version: "3"
services:
  elasticsearch:
    container_name: elasticsearch
    image: docker.elastic.co/elasticsearch/elasticsearch:7.15.1
    ports:
      - '9200:9200'
    ulimits:
      memlock:
        soft: -1
        hard: -1
      nofile:
        soft: 65536
        hard: 65536
    environment:
      - xpack.security.enabled=false
      - discovery.type=single-node
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
    healthcheck:
      test: [ "CMD-SHELL", "curl --silent --fail localhost:9200/_cluster/health || exit 1" ]
      interval: 30s
      timeout: 30s
      retries: 3

I see we don't expose that configuration so it's impossible to achieve the same thing with testcontainers

Hey @nhatthm thanks for this contribution. It LGTM, although I'd like to see tests checking the new behaviour. Would you mind adding them? Thanks in advance!
