Update SDNC CSIT for Honolulu changes

Update SDNC CSIT for Honolulu changes

Added env settings needed to start up SDNC container, and updated
URL used to retrieve list of APIs (which changes in OpenDaylight Aluminum).
Removed unneeded code to start up cert service (since those certs
are not needed for NETCONF/TLS ... the certs we need are for
the NETCONF device itself).  Commented out tests of TLS connection
for now - simulator we had been using no longer exists (docker
is no longer in nexus3.onap.org) and connection to new simulator
is not yet working.  Will restore those tests in a separate commit
after debugging with new netconf simulator.
