Customize jenkins.default by template

Turn jenkins.default to a template. This enables to customize it
easily. This is useful for downstream projects where it is needed
to tune jenkins.default parameters. Either Pass the required
parameter to jenkins class or pass a customized jenkins.default
file location in jenkins_default.
For backward compatibility, default values are set in the class
parameters list.
