[DrupalCI Integration] Enable contrib testing

First (untested) cut at DrupalCI integration for contrib testing. Should be compatible with the current 'dev' branch of the DrupalCI test runner.

Deployment

Staging only, remove all non-core jobs:
SELECT * FROM pift_ci_job j INNER JOIN field_data_field_release_project rp ON rp.entity_id = j.release_nid AND rp.field_release_project_target_id <> 3060;

Remove queued contrib issue tests:
SELECT * FROM pift_ci_job j INNER JOIN field_data_field_release_project rp ON rp.entity_id = j.release_nid AND rp.field_release_project_target_id <> 3060 WHERE j.target_type = 'file';

Remove duplicate queued contrib branch tests:
SELECT * FROM pift_ci_job j INNER JOIN field_data_field_release_project rp ON rp.entity_id = j.release_nid AND rp.field_release_project_target_id <> 3060 WHERE j.target_type = 'branch' AND j.job_id NOT IN (SELECT max(job_id) FROM pift_ci_job j INNER JOIN field_data_field_release_project rp ON rp.entity_id = j.release_nid AND rp.field_release_project_target_id <> 3060 WHERE j.target_type = 'branch' GROUP BY j.release_nid);
