WIP: CLOUDP-318525: Add build_tag_id_prefix and deprecate pin_tag_at

[SimonBaeumer]

Summary

This change intends to avoid overwriting existing tags. Additionally I should preserve the ability to distinguish tags for periodic and release builds.

New build tags:

• Release: 0.9.0-b20250512T000000Z-release-amd64
• Periodic: 0.9.0-b20250512T000000Z-peridoic-amd64

ToDo

• Add unit test
• Clarify tag structure: release-YYYYMM..-amd64 vs YYYYMM-release...-amd64
• Clarify periodic vs nightly naming
• Calrify removal of pin_tag_at

Proof of Work

Questions
