Bamboo remote agents should support the use of TLS - SNI

We have a remote agent that is connecting to a bamboo server instance that is configured using TLS - SNI. The agent throws an exception indicating that the host name of the self-signed certificate doesn't agree with the actual host name (indicating an SNI) issue. If the remote jar uses Apache HTTP components less than 4.3.2, it will need to be upgraded.

We were lucky enough to be able to configure the server around the problem, but if that were not possible (and in some environments it will not be), then we would not have been able to user remote agents.
