/**
 * This is the client service for applications to work with the registry.
 *
 * It does not set up the root paths for the registry, is bonded
 * to a user, and can be set to use SASL, anonymous or id:pass auth.
 *
 * For SASL, the client must be operating in the context of an authed user.
 *
 * For id:pass the client must have the relevant id and password, SASL is
 * not used even if the client has credentials.
 *
 * For anonymous, nothing is used.
 *
 * Any SASL-authed client also has the ability to add one or more authentication
 * id:pass pair on all future writes, and to reset them later.
