627cb49 Extend CALessBase::installer_server to accept extra_args

Authored and Committed by rcritten a year ago
    Extend CALessBase::installer_server to accept extra_args
    
    Allow callers to pass abitrary extra arguments to the installer.
    
    This is useful when using a CALess installation in order to
    speed up tests that require a full install but do not require
    a full PKI.
