Konstantina Chremmou c5b0af533e Removed methods GetHostBootTime and GetHostAgentTime because they duplicated logic
in the Host extensions. Moved method TryResolveWithTimeout to the Connection class
where it is more relevant. Removed wrapper methods WaitForReboot and WaitForAgent
as they were not particularly useful.
