Add docker-compose.yml to repository

[Gershon-A]

This is a good idea to have the docker-compose.yml as we have on other's repo (https://github.com/testproject-io/java-sdk/tree/master/.github/ci/docker-compose.yml) for this repo as well.

version: "3.1"
services:
  testproject-agent:
    image: testproject/agent:latest
    container_name: testproject-agent
    depends_on:
      - chrome
      - firefox
    environment:
      TP_API_KEY: "${TP_API_KEY}"
      TP_AGENT_TEMP: "true"
      TP_SDK_PORT: "8686"
      CHROME: "chrome:4444"
      CHROME_EXT: "localhost:5555"
      FIREFOX: "firefox:4444"
      FIREFOX_EXT: "localhost:6666"
    ports:
    - "8585:8585"
    - "8686:8686"
  chrome:
    image: selenium/standalone-chrome
    volumes:
      - /dev/shm:/dev/shm
    ports:
    - "5555:4444"
  firefox:
    image: selenium/standalone-firefox
    volumes:
      - /dev/shm:/dev/shm
    ports:
    - "6666:4444"

@Gershon-A The reason we have it in other SDKs is because we run GitHub actions CI to test the SDK. C# being not open source, has no source to build in this repository, therefore what is the point to have this kind of files here?

Hello, I'm preparing some basic Jenkins pipeline to show our customers how to automate testing. The flow is: Clone repo > bring up docker stack (from docker-compose.yml) > run test. I'm trying to use our repo as a source for example. And currently, this is not possible. Let's take this to offline conversation.
