Allow job template to say jobs should fail if their parent(s) fail.

(Relates to HPC Pack 2019, 6.1.7531.0 and probably earlier)

#### Feature Request Description

* Using `job submit` on the command-line, we can set `/parentjobids` and have a job queue until other job(s) finishes. This is really useful.

* By default though, if the parent job fails, the child job remains in the queue and never execute, so we have to cancel those jobs manually.

* I'm not quite sure if `/faildependenttasks` fixes this - since I am talking about jobs mainly, rather than tasks. Perhaps it does.

* If it does, then it would be good if `/faildependenttasks` could be set as true by default, at the job template level.

#### Describe Preferred Solution

Option to select Fail Dependent Tasks (or jobs?) in HPC Cluster Manager, in Configuration -> Job Templates -> Job Template Editor -> Add (property) drop down. We already have "Fail on Task Failure", but not "Fail if parent tasks/jobs fail"

#### Describe Alternatives Considered

Alternatively - I cannot really see a reason why you wouldn't want /faildependenttasks to be on all the time. Presumably it makes no difference if there are no dependent jobs, but I think it's reasonable that all child jobs fail by default if the parent fails.
