Provide integration tests for the key functionalities

[konstantina-gramatova]

The tests must cover the key component functionalities and use cases:

• digital twin commands create, modify, delete, retrieve on:
  • thing level
  • feature level
  • feature property level - all properties, single property
  • feature desired property level - all properties, single property
• digital twin command responses
• digital twin command events
• thing auto-creation
• synchronization with the backend i.e. all things are up to date on the backend

Remark, there are a bunch of headers that are used by Ditto but not used by the local digital twins. For example, ditto-originator is one good example. This header can be used as a marker that the message is originating from Ditto, not local digital twins.
