Add include-on-hold option to treat on-hold workflows as running in queue

[tkoft]

Manual approval jobs in CircleCI often are used to block workflows. This change prevents later workflows from running while a previous one is still on hold for manual approval.

For pipelines that just need to ensure jobs don't run concurrently and don't care what order workflows finish in, this option is by default set to false (the current behavior).

Thanks for the submission! I will run it through a test tomorrow and if it works we can merge it in!

My bash incompetence is showing, went ahead and fixed those shellcheck errors :)

@tkoft will you try to test out the preview orb #13 (comment) and let us know how it goes?

I also have allowed forks to run CI now so let's see if there are any additional changes that will kick off CI.

@tkoft , have you been able to verify this works as expected?
