feat: add shadows on interaction

[ghost]

Description of changes: This commit introduces a new feature "add shadow on interaction". When this feature is enabled, ShadowManager adds things shadows to synchronize configuration once it receives a GetThingShadow / UpdateThingShadow request. Similarly, the shadows, which were added on interaction, will be removed from the configuration if there is a DeleteThingShadowRequest.

Why is this change necessary: This change is necessary to allow other components to dynamically add and remove thing shadows to/from sync configuration without Nucleus restart.

How was this change tested:

• Unit tests added
• Integration tests - in progress
• Manual testing done on GG Core device

Checklist:

• [ ] Add integration tests
• [x] Add new configuration option to enable / disable sync on interaction feature
• [ ] Updated the README if applicable
• [x] Updated or added new unit tests
• [x] (N/A) If your code makes a remote network call, it was tested with a proxy
