Per host encryption

This release brings a brand new feature which allows end users to choose individual servers that can accept un-encrypted communication. The feature is split into two different configuration options, which consist of a boolean flag and a list of trusted servers/subnets to accept traffic from.

The theory is as follows:

• The destination server must have un-encrypted communication enabled.
• The destination server must consider the source server as trusted.

The above allows for the ultimate in granularity over which servers can communicate in an un-encrypted fashion. While also guaranteeing security of the rest of the end-users servers.
