Remove Session for the strategy interfaces

[quaat]

This a proposal of an enhancement to the OTEAPI-CORE project that could streamline the development process and improve the overall architecture. The proposal is centered around simplifying the strategy implementation by removing the session object from the strategy interface. The service, or a core-module, can have the responsibility for reading and updating the session information.

Proposed Change:
Remove the session object from the strategy interface. Instead, we can centralize the logic for reading and updating the session to the OTEAPI service. This change would lead to a cleaner and simpler strategy implementation, remove the need for boilerplate code for configuration updates and error handling.
