Create guice module to bind LockService interface from SPI to LockServiceImpl

[cwperks]

Description

Quick follow up from #714 to solve a dependency injection issue resulting as the change of LockService from a class to an interface. Since JS returns LockService from createComponents, it also needs to bind the interface to the concrete class to let Guice know how to do the dependency injection.
