Virtual jobs does not honor freeze windows

[sagar1312]

What happened:
Changes were made in this PR #3131 to skip execution of job with the annotation screwdriver.cd/virtualJob: true.

But this change did not take freeze windows in to the consideration. Due to this, the virtual jobs are skipped execution and marked as 'SUCCESS' with in the freeze window.

What you expected to happen:
Queue the virtual jobs with freeze windows for execution.
Queue Service should pick this up outside the freeze window, skip the execution and mark the status as 'SUCCESS'
