Explore the solutions to support ELifetimeCondition and handover properties

[indiest]

What

As of v0.6, ChanneldUE doesn't support replicated properties with ELifetimeCondition - ALL properties are replicated between all interested servers and clients.

Some states that should be only replicated between the spatial servers (e.g. the FBodyInstance) are also replicated to the clients as long as the states exist in the channel data.

This task is to find and design the way(s) to resolve these problems.

Why

• Some properties are not needed to be replicated the owner/proxy side. Avoiding the replication can save the bandwidth;
• Some properties are not meant to be known to the client / simulated proxy. The replication should avoided in order to protect the privacy. For example: the APlayerController
