Check available jobs (managed OH)- BED-9512

[StranDutton]

Ticket: BED-9512

Adds support for the new /api/v2/collector-job-queue/available endpoint in BHE for SpecterOps-hosted OpenHound instances. This PR only adds the function that calls the new endpoint, but it is not wired into the scheduler yet. Future work will wire this call to the regular poll once we make more progress on the managed/unmanaged logic split.

Summary by CodeRabbit

• New Features
  • Managed deployments can retrieve queued collector jobs from the service.
  • The scheduler can check for available managed collector jobs and return the next queued job.
  • Collector job details, including scheduling, retry, claim, execution, and parameter information, are now supported.
• Reliability
  • Queue polling uses bounded request timeouts and validates responses.
  • Empty queues are handled without disrupting scheduling, while request failures are logged and surfaced for recovery.

Walkthrough

The change adds typed managed collector job responses and client polling. It separates managed queue checks from standard scheduler polling. Tests and fixtures cover routing, parsing, errors, timeouts, empty queues, and logging.

Changes

Managed collector queue

Layer / File(s)	Summary
Collector queue API and models src/openhound/core/clients/bloodhound_enterprise.py, src/openhound/core/clients/models/jobs.py	Adds collector job response models and available_collector_jobs. The client encodes the job filter, uses dedicated timeouts, validates responses, and re-raises request errors.
Managed scheduler handling src/openhound/scheduler/service.py	Separates managed collector queue checks from check_jobs. Standard polling now uses the standard jobs endpoint and starts returned standard jobs.
Scheduler coverage and API fixtures tests/test_bhe_job_scheduling.py, tests/test_data/api/jobs/*	Adds mock queue endpoints, managed-mode fixtures, response fixtures, and tests for request parameters, parsing, empty queues, running jobs, errors, recovery, timeouts, and logs.

🟠 Major · Restore managed queue polling in _poll(). · service.py:325

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Restore managed queue polling in _poll().

When managed mode is active, _poll() calls check_jobs(), so it never calls check_managed_collector_jobs(). Restore the managed branch and add an idle managed-mode _poll() test.

Do not pass the returned CollectorJob to _start_job(). The current managed lifecycle has no claim/start operation, and _start_job() accepts the standard Job contract.

-                if available_job:
-                    self._start_job(available_job)
