Project clean up

• Clean up the project
• New folders:
  • internal: for docker & build scripts, manifest
  • src/views
  • src/views/partials
  • src/views/partials/widgets
• Widgets are imported on src/views/partials/widgets.pug instead of on each file requiring them (avoid dup after build)
• Upgrade Cypress to 5.6
• Clean up the Readme
• Depreciate un-federated config.json in favor of the config.federated.json
• Use native pug config file for config.json import
• Use Parcel instead of custom scripts, bundling less things, smarter, faster and cleaner
• Split dependencies file into index.pug, dependencies.pug and context.pug
• Removed the need to call [...]/index on sass
• Removed cypress-terminal-report dependency

Overall, is retro-compatible and should not have any impact on developments.

Please notice that the project is now using terser instead of babel.
