Make Webhooks configurable on a per folder basis
Description
We use a single project to organize a couple of Dockerfiles and let them build to container images automatically via Webhooks to OpenShift. We organize the Dockerfiles in subfolders, like for example centos, ubuntu, alpine, ... Problem is that when we want to use Webhooks, all builds for all subfolders are being triggered on every push causing lots of unnecessary builds in OpenShift. Using a project for each Dockerfile creates too much overhead and makes it hard to handle.
Proposal
Allow to set a webhook per folder, for example under integrations -> webhooks -> trigger --> "restrict event to folder [choose folder XYZ]"
