Execute Web Trigger

As a developer, I am able to start a Work that is configurable enough to start a build on Openshift.

Openshift: https://openshift.prod.nuxeo.io/console/
API doc: https://docs.openshift.com/container-platform/3.11/rest_api/build_openshift_io/buildconfig-build-openshift-io-v1.html#apisbuild-openshift-iov1namespacesnamespacebuildconfigsnameinstantiate 

 Steps:

• Ask a PS to have test Openshift CI/CD
• Use postman to trigger a build on this real Openshift instance
• Implement the Worker with configurable params : distinct the job params and and the project/branch params (commit id)

AC:

• I have a Work I can schedule with a minimal set of parameters that is able to start a remote build on Openshift (Nuxeo Dev Sandbox).
• The parameters required to start a Work helps to define what are the options we need to expose through the other screens.
