Please provide per Jenkins-Project Key setting

[mfriedrich74]

I would like to get the ability the change the KEY-json field which is sent to the Stash server on a per project basis. Basically i want to be able to set the same Key for several Jenkins projects which map to the same Stash repoitory.
The Key should default to the Project name, but be editable.

But right now i dont find the time - may be i can start in a few weeks.
