Initialization and Synchronization of Ditto Thing

[RaiBnod]

BoneScript micro-service will start on edge device and it consists H2 database for storing the Ditto Thing. To sync that database content and the edge device, we need to do care of following two things:

1. For the first time initialization: it should able to create skeleton ditto object and start the process.
2. If already initialized: we need to read the points from DB and set those values.
