Description

Currently the SecurityTokenProvider interface and its implementations provide a read-only interface to access the security tokens; for the Unmanaged AM mode when the Driver runs in the same process as the Client, we need the ability to add new security tokens to the user's credentials. For that, we need to implement the .addToken() method and provide a mechanism to serialize such tokens.
