Skip Region Load Checking in is_remote_task

[javanlacerda]

This change adds a way to skip external region load queries (get_region_load) when we only want to verify if a task is configured to run remotely (e.g. via is_remote_task / is_remote_utask), preventing unnecessary external calls and speed issues.

Changes

1. Added should_check_regions Parameter to _get_subconfig

• File: service.py
• Change: Introduced an optional should_check_regions (defaulting to True) argument. When it is False or no queue_check_regions are configured, we skip checking region workloads entirely, log the reason in a single consolidated log statement, and immediately return a weighted subconfig.

2. Propagated in _get_specs_from_config

• File: service.py
• Change: Propagated should_check_regions to the _get_subconfig helper.

3. Disabled Region Checks in is_remote_task

• File: service.py
• Change: Passed should_check_regions=False when calling _get_specs_from_config inside is_remote_task since workload size does not affect task remote configuration validation.
