Promote packages between stages

[ruflin]

Idea

Use Jenkins pipelines wherever it's possible model the (semi-)continuous delivery solution, that will help with releasing.

Release stages

With #86 the package-storage has 3 release branches: production, staging, snapshot. Packages can be promoted from one branch to an other. This looks as following:

snapshot -> staging

• select package
• add to staging
• remove from snapshot
• run checks for staging
• run checks for snapshot
• push changes to staging
• push changes to snapshot

Important is that changes are only pushed, if both checks/CI passed.

staging -> production

• select package
• add to production
• remove from staging
• run checks for production
• run checks for staging
• open PR to master + CI
• If PR is merged, remove from staging

---

Notes:

The main difference here is that there is manual PR involved. It would be great if this PR would contain a diff in the PR description between the current and previous package.

An initial draft of such a script for the snapshot->staging part was opened here: #110 It does not contain all steps yet.
