Refactoring Examples for Chapter 2, including examples of packaging and adding automation

[salaboy]

This issue is a checklist for all the changes that we need to apply to projects to make sure that the examples align:

• For Projects (fmtok8s-api-gateway, fmtok8s-c4p-rest, fmtok8s-agenda-rest, fmtok8s-email-rest):
  • Move from master branch to main branch
  • Add Github Action automation (at least build and publish container to Github registry) #22
  • Add publish helm package steps on continuous integration worflow #28
  • Add checks and validations.. codecov, codelints, PR validations, etc.
  • Refactor the Projects structure to have the following directories (start with api-gateway) :
    • config/ contains Kubernetes manifests that can be applied with kubectl apply -f (this can be generated based on the helm charts, to keep them in sync)
    • helm/ helm chart definition for the project, you should be able to build the chart using helm build . #26
    • carvel/ contains the configuration for a carvel package following: https://carvel.dev/blog/carvelize-helm-chart/
    • remove jenkins x directory
    • Update to Spring Boot 2.6.4 and Spring Cloud 2021.1.1, update to Java 17 #24
    • When possible use mvn spring-boot:build-image to construct the container #34

@mcruzdev the idea here is to have a task list for changes in all projects, but we should start by one.. the most complex project so far is the API Gateway so I would start there.. If you have enough rights, make sure to change the master branch for the main branch first.. before doing the automation.. so we can do everything from main

Notice that each task (checklist) have a button to create an issue to track that work.. feel free to create those issues from the checklist if that helps.
