Description

This pull request adds support for the Feldera database engine to the project. The changes include introducing a new Feldera connection configuration, implementing a Feldera engine adapter, registering the Feldera dialect, updating dependency and test configurations, and ensuring the new engine is integrated throughout the codebase.

These changes collectively enable SQLMesh to connect to, generate SQL for, and manage pipelines in Feldera, with appropriate configuration, dependency management, and test coverage.

Test Plan

Tested locally against a Docker Feldera instance with 10+ models, including tables, views, and materialized views. Verified end-to-end behavior for model deployment, query execution, and data ingestion.
