Add a gradle task to scaffold new feature services

[jkerr5]

Something like newService with the following parameters:

• name - <string> The service name
• configName (optional) - [string] A top-level configuration name that services can be grouped under. If not specified the service name will be used for the config name.
• searchApi (optional) - [true|false] Whether or not the service should have a configuration to support the MarkLogic search API. This is used primarily by the ArcGIS Pro add-in. Defaults to false.

Note

Service name must be a string that is a valid part of a URL path. There should be more checks to make sure this is the case but there are not right now.
