Title: Added a BuildParameterFactory to get all Nodes for a Label

The AllNodesForLabelBuildParameterFactory gives all Nodes for a Label and returns a NodeLabelBuildParameter for each. An usecase would be to execute a job on all nodes having label test-system to deploy an application which scales by deploying the same configuration over and over again. By using this factory you only need one Job triggering the deployment independent of the number of nodes you want to deploy to.
