Add docker example and documentation.

Some key features:

• Script for automating the build of an ultrack image based on the current pypi version and available torch pre-configured containers.
• Installation of cucim and its dependencies on GPU supported containers.
• Tutorial on serving jupyter notebook inside the container.
• Tutorial on using the Gurobi WLS license.
• README documentation

But some minor issues might be addressed:

• Ultrack installs nvidia related libraries even when not asked, which creates bloated CPU containers.
• Ideally, the README should be on the documentation page.
• We must create a royerlab or ultrack page on DockerHub.

Hi @ilan-theodoro , sorry for the delay to review this.
I don't have any major comments, everything looks great.

I agree with both points, could you include them in this PR?

• Ideally, the README should be on the documentation page.
• We must create a royerlab or ultrack page on DockerHub.

Ultrack installs nvidia related libraries even when not asked, which creates bloated CPU containers.

I think using

pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cpu

before installing ultrack will install torch with CPU only

I created #171 to fix the CI issues

@ilan-theodoro great PR.
I moved the position of the docker on the documentation because I want people to use it as a last resource.
Any comments?
Otherwise, I think we can merge this; thanks for this PR.
