Rename this project

It is the tiniest little nit, but I feel like this project should be named 'base-images' instead of 'container-images', so I'd like to propose that we rename it.

My understanding of the purpose of this project may be flawed, so I'll describe how I have been thinking about it as a rationale for changing the name, to see if there is a flaw or not.

My running assumption is that this project contains the bits to build and provide basic container images that other tor projects' DockerFiles can use to build with (in particular Debian based images). The idea being that its better to have our containers pulled from our infrastructure, rather then from DockerHub, where we get rate limited, and we don't have any way to 'trust' their images. Although the DockerHub images are built by Debian developers, we don't have any functional mechanism to validate the built images are what those DDs expect them to be when we pull them. There has been work done on this in the past, but my understanding about the current state is that it is not functional, and we cannot rely on it.

Projects can use these in their own DockerFile as FROM lines, to build on top of them for whatever their needs are. For example, take the base container from here, note it in the project's DockerFile with FROM, and then add the necessary build dependencies into the Dockerfile, producing a container that can be pushed into that project's registry for CI build purposes.

I think that this project should only have the base containers that TPA is willing to build and maintain themselves, and each project then builds and maintains its own images off of these, and maintains those in their own registry, and not here.

If we call this project "container-images" its very generic and suggests that this project could be used for all kinds of images, but I think the more narrowly scoped 'base-images' is a more accurate name in alignment with how I understand this project, so I wanted to see what you think in case you were thinking that this project should be used for something more than just base images.
