> Today, CassandraRoleManager uses hardcoded checks to determine if the node is configured to use PasswordAuthenticator, to determine whether to enable additional supported and alterable role options such as PASSWORD, HASHED_PASSWORD, etc. needed by that authenticator.
> To enable negotiated authentication, nodes will enable multiple authenticators to be configured, which may individually define additional supported and alterable role options. Rather than hardcoding authenticator-specific logic in CassandraRoleManager, extend IAuthenticator with defaulted methods for allowing authenticators to return their supported/alterable role options and let CassandraRoleManager fetch them through that interface.
