tf-daily: new job that triggers tf-main and tf-coverity jobs

A new job is introduced, tf-daily, triggering tf-main and tf-coverity
jobs in a daily basis (not weekends). Manual trigger is
also possible, allowing to test a specific git reference.

The tf-coverity cron-trigger is removed, so tf-daily would be the
trigger for the latter.
