fix:Termination of pull transfer process from consumer side not succe…

[AndrYurk]

…ss in real but stated as "TERMINATED"

What this PR changes/adds

Run termination process from data flow manager for provider when termination initiated by consumer

Why it does that

During termination PULL transfer process from consumer, system does not call method terminate() from DataFlowManager on provider side.
As a result process not terminated in real but transfer process had state "TERMINATED", and then it is not possible to initiate terminating process again not from consumer neither form provider side.

@AndrYurk do NOT submit surprise PRs. Our PR Etiquette clearly states to submit a discussion or an issue first.
Committers need a chance to look at the issue and triage it.

Also, your code does NOT come with any sort of testing. I recommend closing this, following proper procedure and then opening another PR that will pass muster.

Oh, and you need to sign the ECA.
