IDM 6.0.0.5 connects to external DS repo using TLSv1

Reported on IDM 6.0.0.3, also reproducible on IDM 6.0.0.5. Does not affect IDM 6.5.0.

IDM 6.0.0.x with external DS repository.

If IDM is configured to use SSL (in repo.ds.json):

"connectionSecurity" : "ssl",

IDM connects to DS using TLSv1.

--------

This appears to be due to this DS bug that was fixed:

OPENDJ-5553 : Rest2Ldap cannot connect to TLSv1.2 servers

The bug is fixed in DS 6.5.0, and 6.0.1.
IDM 6.0.0.5 is using opendj-core-6.0.1-M2.jar, which does not include the fix.
