Implement UI support for Global Configurations

[bhufmann]

Feature Description:

This tracker is for the support of global configurations in the vscode-trace-extension UI. Global configuration is explained the here.

Updates in the traceviewer-react-component that is part of the theia-trace-extension repository are expected together with the VsCode UI integration similarly to #318.

To support global configuration using the json editor the following items have to be implemented

• Manage Global configuration
  • Add a vscode command + a button/menu into the "Opened Traces" view:
  • This will open a new web-vew. The web view will use the Configuration Endpoints as described here
• Use Cases
  • Open global configuration web view
    • Get all configuration sources from BE
    • Fill drop-down menu with all configuration sources. Select one (alphabetical)
    • Execute Use Case: "User selects configuration source"
  • User selects configuration source
    • Get all configuration instances from selected source from BE
    • Show all configurations as a list
    • Each configuration will have an "Edit..." and "Delete" button
    • There will be a "New..." Button to create a new instance
  • User presses "New..." Button
    • Json Editor is opened with pre-filled content according the schema
    • User fills in content
    • JSON Editor supports validation, saving, loading and applying configuration (the same way it does for data provider configuration)
    • User applies configuration
    • Execute Use Case "User selects configuration source"
    • Refresh trace viewer (e.g. Available views view)
    • Close Json Editor
  • User deletes configuration
    • User presses delete button of a configuration
    • Execute Use Case "User selects configuration source"
    • Refresh trace viewer (e.g. Available views view)
  • User edits configuration
    • Get JSON for configuration instances
    • Open JSON editor for configuration instance
    • User does updates
    • User applies configuration
    • Execute Use Case "User selects configuration source"
    • Refresh trace viewer (e.g. Available views view)
    • Close Json Editor
  • Close configuration webview
    • Close open json editor
    • Make sure that content in editor is not lost (e.g. ask user to apply)
• Notes
  • Consolidate json editor implementation for global configuration and data provider configuration to not duplicate code
  • Handle adversarial cases
