Add workshop

[omshinde]

The pgRouting Workshop for FOSS4G 2021 Argentina has been released as v2.7.0.
@cvvergara and I thought it would be good to have it available as part of the Docker image.

@cayetanobv , May we please know your opinion? Is it possible?

Hi @omshinde . Including the workshop inside the main Docker images is not a good idea. One of the main destinations of these Docker images is servers where it's very important to keep the image size as tiny as possible. We can get the same goal by preparing a Docker-compose YAML file using the main Docker image but setting a volume that includes the workshop. We can include a section in this repository about how to use it. I can help you with all of that. We can also write a note about that in the workshop repository. What do you think?

Hi @cayetanobv
I agree with you on the thoughts about not including the workshop in the main Docker image, it will increase the size of the image by many folds. Also, preparing a docker-compose YAML file seems great to me. It is easier to work and a separate volume can be associated for the workshop. Thank you for your help and please let me know on how to get started with this. I will also post this on pgRouting Gitter so that the community can pitch in with their thoughts.
