Modularize Telemetry component

[a-thaler]

Description
The telemetry component of the kyma project covering the configurable logging and tracing feature needs to be transformed into a kyma module. This epic will take the initial plan into reality by managing and tracking the actual action items.

Actions

• Initial Development
  • Fluentbit managed by operator: Fluentbit lifecycle managed by telemetry-operator #15955
  • Extract modules from kyma repo
    • Setup repo (Setup individual repository for telemetry-operator #16745)
    • Switch to new repo (Setup individual repository for telemetry-operator #16745)
    • Move size-exporter and webhook-cert-init component (extract directory-size-exporter to dedicated repository and integrate webhook-cert-init to telemetry-manager #16852)
  • Create/generate kustomize files and have basic deployment test (Manager deployable with kustomize #16909)
  • Remove production profile [Telemetry Manager] remove production profile #16853
  • Integrate module-manager interface to have module status (Implement module contract in telemetry-manager telemetry-manager#36)
  • Transform component into a module: Create a first module definition and deploy the module with the new lifecycle-manager telemetry-manager#35
  • Implement module release pipelines ([Telemetry] Module verification and release process telemetry-manager#113)
• Mandatory items for a rollout with test users
  • Test a migration, assure that all resources are covered (Verify migration to new telemetry module approach #17375)
    • rename base resources (Rename manager deployment name to existing name telemetry-manager#144)
    • webhook handling ([Telemetry Operator] Keep webhook CA bundle stable over Pod restart and webhook modifications #16626)
    • copy missing resources (Migrate leftover helm resources to kustomize telemetry-manager#150)
  • Migrate documentation (Document the Telemetry Module #17468)
  • Namespace-agnostic ([Telemetry Manager] Namespace-agnostic manager #17195)
  • Migrate priorityClass: [Telemetry Manager] add priority class #17157
  • Deletion logic: [Telemetry Manager] Do not delete module until all resources are deleted #17162
  • Move the loki CR of logging component as a managed object of the telemetry module ([Telemetry] Optional Loki LogPipeline #17549)
• Mandatory items for a productive usage
  • Link to documentation as part of moduleTemplate
  • Namespace scoped module CRD (Namespace Scoped Telemetry CRD telemetry-manager#286)
  • Improved release notes (Improved release notes telemetry-manager#287)
  • Advanced status: [Telemetry Manager] Reflect state of managed component in module status #17158
  • Transform integration tests to be based on kustomize and located inside the repo
    • Document the test strategy (Initial documentation for modular telemetry telemetry-manager#175)
    • add basic setup (Add end-to-end tests telemetry-manager#44)
    • add basic tracing e2e test ([Telemetry Manager] E2E trace test based on new setup having no dependency to jaeger telemetry-manager#57)
    • add missing trace filtering test (Missing trace tests for filtering noisy spans telemetry-manager#410)
    • add missing secret rotation test (Add missing test for secret rotation for trace, metric and logs telemetry-manager#411)
    • add basic metrics e2e test ([Telemetry Manager] E2E metric test based on new setup having no dependency to a backend telemetry-manager#72)
    • add basic logging e2e test
      • First POC: PoC: Mock backend for logging E2E test telemetry-manager#184
      • basic log scenario (Add initial logging tests telemetry-manager#237)
    • add missing additional logging tests (Missing log tests to get rid of fast integration tests #18015)
      • Log Parser (Add more e2e logging test telemetry-manager#285)
      • Input (Add more e2e logging test telemetry-manager#285)
    • add istio dependency test
      • Concept (E2e test concept covering istio and backend dependencies telemetry-manager#261)
      • access log test (Basic istio access logs test telemetry-manager#288)
    • add upgrade test (Basic upgrade test telemetry-manager#213, Enhance upgrade tests telemetry-manager#236)
• Cleanup
  • Remove component docu from kyma repo docs (docs: Remove content from telemetry component docs and refer to new module docs #18042)
  • Remove fast-integration tests related to telemetry (Cleanup telemetry component #18190)
  • Remove telemetry component + CRDs from kyma repo, remove component from component lists (Cleanup telemetry component #18190)
