feat(core): Added ServerContainer

[Tranquility2]

As part of the effort described, detailed and presented on #559 This is the seconds PR (out of 4) that should provide all the groundwork to support containers running a server.

This would allow users to use custom images:

with DockerImage(path=".", tag="test:latest") as image:
    with ServerContainer(port=9000, image=image) as srv:
        # Test something with/on the server using port 9000

Next in line are: feat(core): Added FastAPI module feat(core): Added AWS Lambda module

---

Based on the work done on #585 Expended from issue #83

some thoughts:

1. can you rename as ServerContainer
2. can we make this a module under modules? I guess if we do this we have to figure out how to make those modules depend on each other but assuming we can make that work, how do we feel about this.

Yes, you are right, ServerContainer is a much better name and it correlates to your second point, I do think its very general and more in par with DBContainer than a specific module (thats why I placed it under generics). I think the modules should remain specific product related. I'll try and support my claim with the java implementation of "nginx container" (which I'll probably add later on 😅 ) https://github.com/testcontainers/testcontainers-java/blob/6658a2c0a880d01c6d402ea9a4cb5f72eb15083c/modules/nginx/src/main/java/org/testcontainers/containers/NginxContainer.java#L12C13-L12C29 Notice it uses GenericContainer which is (in a way) the combination of DBContainer and ServerContainer.

So to conclude I think we should keep ServerContainer under generics, and maybe plan in the future to merge DBContainer and ServerContainer (?) into GenericContainer (but to be honest I think the separation is good at this stage)

[alexanderankin]

for context, we are trying to remove DbContainer as well.

will take a look.

I can offer another alternative, completely skip ServerContainer and just make the modules repeat some code, I can also check it out and propose a draft if you like. (with ServerContainer I tried to create something useful, maybe I just missed the big picture / context)
