> 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.
