    IDP-1793  Use Suppliers for HttpRequest/Response
    
    https://shibboleth.atlassian.net/browse/IDP-1793
    
    net.shibboleth.idp.authn.impl.StorageBackedAccountLockoutManager.UsernameIPLockoutKeyStrategy
    
    Gains a setter/getter for a Supplier for the HttpServletRequest
    and loses the setter for the raw object.
