[EPIC] Tasklist is included to Single Jar/distribution

[romansmirnov]

Introduction

Based on #17062, Tasklist will become part of the Single Jar (that already includes Zeebe and Operate).

Breakdown

• Preparete Tasklist dependencies to align with Zeebe's
  • Clean-up Tasklist maven dependencies: enable dependencies analyse and convergence plugins
  • Bump java version to 21
  • Integrate Tasklist into maven multi module structure
• Add Tasklist to current Zeebe distro
  • Add tasklist.sh script to start only Tasklist
  • Resolve conflict with Operate's migrate.sh script
  • Remove obsolete tasklist-distro folder
  • Ensure that the correct index.html is served (because the Single Jar bundles multiple webjars containing an index.html)
  • use different webapp application configuration files per component
  • logs mount for unpriviliged user in tasklist.Dockerfile
• Include Tasklist in the unified release workflow
• Update helm and camunda-operator with configuration files changes
