Description
At the moment the module does not support gcm mode. In order to keep backward compatibility, I suggest we introduce a directive which allows us to switch between cbc and gcm mode. By default, CBC should be enabled in order to keep backward compatibility.

Research direction
Start by reviewing PR 24 and the module's existing CBC handling. Define how the proposed encrypted_session_mode directive selects GCM or CBC while keeping CBC as the default. Done means the module supports GCM mode and preserves backward-compatible CBC behavior.
