Deprecate javascript and groovyScript params

[chonton]

javascript is used to create the initial (or 'default') field values for the input form and groovyScript is used to create the options map for json-editor. With pipeline available, it no longer makes sense for this plugin to call out to groovy script or javascript. Instead, pipeline code should compute the values and populate params for the extended-choice-parameter-plugin before invoking the input step.

This will deprecate several params. Additionally, during this deprecation, remove @DataBoundConstructor and replace with @DataBoundSetter as described in Writing Pipeline-Compatible Plugins
