CICD: Continuous integration and continuous delivery

[sirfifer]

This is a discussion start on the CICD topic.

It might make sense to move this to its own category, but for now we can just use this thread.

I also thought of putting it in ideas, but I think that should be for completely new stuff that we are unsure if we will do or use.
While it is very unsure how far we will go with CICD as a team, we will be doing some and will likely continue to evolve this space into the future.

At its core this is not only an Agile method, but a solid method from a quality, reliability and security perspective.

Here is a great simple definition I found

Continuous integration and continuous delivery (CI/CD) is a software development approach where all developers work together in a shared code repository of code. As developers make changes, automated processes detect code issues. The outcome of using CI/CD is a faster development lifecycle with lower error rates.

I'll continue to add more here as time permits.
