JBS Modification Proposal: Don't inherit master bug labels when creating backport records

[Seán Coffey]

Since the launch of the OpenJDK Jira Bug System, the default behaviour 
of the manual "Create Backport" action has been to inherit the master 
bug labels for the newly created backport record. The experience for 
most when manually creating a backport record is to delete all inherited 
labels. In comparison, nowadays, the vast majority of backport records 
are created by bots (e.g. Dukebot) upon pushing a change to a project 
repo. These automated bots don't inherit labels from the master bug. 
That approach fits better since all processes that I'm aware of ask that 
project tracking labels be added to the master bug only.

I'd like to propose a JBS infra change whereby the manual "Create 
Backport" action adopts the bot position of creating backports with no 
labels. Are there any comments/concerns with such a tweak ?

regards,
Sean.
