Allow toggling for an input option to use a property wrapper @MockObservable for RxSwift Observable variables (default is set to no).

To use the @MockObservable, copy the content of https://github.com/uber/mockolo/blob/master/Sources/MockoloFramework/Templates/PropertyMockable.swift into your project, pass in the module name in your project containing the content to the '--custom-imports' option, and pass in '--use-mock-observable' flag to the command line.
