Added a mechanism to check current load (queued and scheduled jobs) in GCP Batch regions. The service now avoids scheduling tasks in regions with a high number of pending jobs (currently thresholded at 5). This is configurable via `queue_check_regions` in `batch.yaml`. This helps in distributing the load more evenly and avoiding delays when some regions are heavily utilized.

Includes comprehensive unit tests for the load-balancing logic and API interaction.

Maybe this could be a config per project?

nit: maybe return like -1 when the get_region_load() fails and check it before logging to avoid confusion by saying that the region has 0 queued.
