The Kerberos authenticator has a feature to replace the "_HOST" placeholder string (if present) in the serverPrincipal with the value of
druid.host.This transformation wasn't applied in getPrincipalFromRequestNew(), this patch changes serverPrincipal such that the host replacement is applied in the constructor and saved.
