Add additional checkbox in Integrator Action for "Test Connections"

Include a new checkbox in Integrator that when checked, the Action just tests the Integrator load/job in the specified project without actually executing the project. The check box should have the same effect as pressing the "Test" button in a component in Integrator. Any message should come back to the feedback process (modal dialog or banner):

When this option is checked, "Execute with parameters" should be greyed out.

This will be used in Solutions models (for testing componentes/connections), instead if having to write a specific small groovy job to do the same.
