[JENKINS-41940] Pipeline stages should be configurable with a weight property, corresponding to the number of executors the stage occupies

For Freestyle jobs, the Heavy Job plugin (see https://wiki.jenkins-ci.org/display/JENKINS/Heavy+Job+Plugin) can be used in order to configure the number of executors that a given job occupies. This is necessary in order to avoid CPU oversubscription when a single build consumes multiple HW threads (e.g. in case of "make -jN", "ninja -jN" etc.).

I have done some research and was not able to find a means to specify the number of executors consumed by a Pipeline stage.

Parallel builds are a necessity in case of large C++ builds, and the ability to specify the number of executors is a practical solution that can be used by the scheduler in order to avoid CPU oversubscription on a particular node.
