Create a configuration class

[aasheptunov]

Create a configuration class.

User story:
As a deveoper, I want to *add a singleton class that would contain the configurations , so that be able to retrieve configuration values from anywhere in the library without having to pass them down the call chain.

DoD:

• A singleton class for storing project configurations has been added and implemented.
• An ADR has been created describing the reasons for this architectural change.
