Hello, it will be very useful to make custom tools installation plug-in allow conditional installation of tools based on job parameters.

e.g. I have a job that can run against Firefox and Chrome. I want chrome installed only if current build parameters suggest that chrome will be used.

This is especially useful when slaves are provisioned just for a single build, e.g. docker/kubernetes. Without such option, the tool will always take time and bandwidth to install regardless current build parameter selection.
