[FAB-6843] Integrating Signing Identity
This change-set does the following: - It integrates the SigningIdentity interface in the TransactionContext class. A SigningIdentity represents the capability of user to sign messages. Indeed, a SigningIdentity instance can be obtanied from an instance of the User interface. This will simplify the integration of different signing algorithms like those offered by idemix.
