Description of problem: Allow to set SSL protocol for external communication (i.e., providers). In order to do that please add a new configuration item, ExternalCommunicationProtocol, that will set the proper SSL protocol.
Verified with rhevm-3.5.0-0.28.el6ev.noarch. satellite 6.0.6 as external provider. SSL communication with provider works with the different protocols configured with engine-config ExternalCommunicationProtocol parameter. Communication fails when setting the parameter with a random value, e.g. 'ivalid'. Verified the communication used the correct protocol with tcpdump.
rhev 3.5.0 was released. closing.
