Ticket 49010 - Lib389 fails to start with systemctl changes
    
    Bug Description:  systemctl changed their api to status which broke the
    lib389 wrapper. Pyldap doesn't work with bytes mode on fedora 24 and python 2.
    Asan would not allow the server to start correctly without the env options
    
    Fix Description:  Change the systemctl interface to use is-active, check pyldap
    for python 3, and add the asan passthrough options.
