New Monorepo structure

[Themezv]

Current structure:

1. apps - applications with "runtime"
2. packages - reusable packages without "runtime"
3. .docker - common and contains docker files for apps
4. docker-compose, key.pem, some files from docs are specific for ligretto, but placed in root of monorepo

Next structure:

1. ligretto - contains all ligretto-specific files and packages
   • ligretto-core-backend
     • .docker
   • ligretto-frontend
   • ligretto-shared
   • ligretto-gameplay-backend
     • .docker
   • docs
   • docker
2. packages - common packages
   • ui
   • analytics
   • eslint-config-memebattle

Technical questions:

• [x] nested workspaces supported by yarn
• [ ] can we move ci configs from root to nested directories?
