feat: taiga plugin

[irfanuddinahmad]

This pull request introduces a comprehensive set of new API files for the Taiga plugin, implementing full CRUD and remote operations for connections, scopes, and scope configs, as well as pipeline plan generation and initialization logic. The changes modernize and standardize the Taiga plugin's API layer, aligning it with the plugin helper patterns used in the DevLake project.

The most important changes include:

Connection Management APIs:

• Implements full CRUD endpoints for Taiga connections, including creation, listing, retrieval, updating, deletion, and both new and existing connection testing with authentication support. (connection_api.go)

Scope and Scope Config APIs:

• Adds endpoints for managing Taiga project scopes and scope configurations, including create, update, retrieve, list, and delete operations for both scopes and scope configs. Also includes endpoints for retrieving projects by scope config and the latest sync state for a scope. (scope_api.go, scope_config_api.go) [1] [2]

Remote API Integration:

• Implements remote API endpoints for listing and searching Taiga projects (scopes) from the Taiga server, with support for pagination and keyword search, enabling dynamic project discovery. (remote_api.go)

Pipeline Plan Generation:

• Adds logic to generate pipeline plans and plugin scopes for Taiga projects based on connection and scope configuration, supporting the new v200 data source pipeline plan format. (blueprint_v200.go)

Plugin Initialization:

• Introduces an initialization function that sets up shared helpers and remote API proxies for the Taiga plugin, ensuring all API modules are properly wired up. (init.go)
