Define process for updating App Template

[TheTechArch]

Description

We need to define a process for updating app template including nugget packages

Considerations

• Alpha vs beta versions of the nuget packages.
• When to update the version in Designer.
• Deprecated functionality
• During patching we might patch dependencies in App.csproj, how are the app owners notified so they can do this to their apps as well?
• How to roll out app functionality that requires changes in the platform code as well? ref. case with multiple pages and platform pdf.

Acceptance criteria

• A documented process for updating app template is available under docs.

Tasks

• [x] Suggest solution
• [x] QA
• [x] Documentation

Suggested solution

Suggested solution: Changes only affecting nuget packages

1. Complete changes in template
2. Get PR approved
3. Push alpha nugets & update reference in Altinn.Apps/AppTemplate
4. Merge to master
5. Complete testing of new feature
6. If testing okay. 7 Create new branch. Push nugets without alpha based on the branch
7. Duplicate changes in Altinn Studio template
8. Update nuget reference in Altinn Studio template.

Suggested solution: Changes affecting platform code as well

1. Code that requires changes in platform are merged in a seperate PR
2. The platform code must be rolled out to all envs before nuget is published
3. If it is a need to deploy this code faster then our regular deploy schedule we can consider a specific deploy schedule for that specific feature
4. Follow steps in "Changes only affecting nuget packages"

Added suggestion for changes where appBase aren't affected: Suggested solution: Changes only affecting nuget packages (not appBase)
