#4053 [HHQ-3890] Add socket timeout to VMware ESXi 4.0.0 plugin

[Hyperic Team]

http://jira.hyperic.com/browse/HHQ-3890
Add a socket timeout to the plugin.

This would allow customer to configure the timeout to 10 seconds or less so that the Agent wouldn't have to wait a long time for the host not to be reachable.

As it stands now, the VMware ESXi 4.0.0 plugin blocks and therefore causes a delay when sending the metrics to the server.

This affects other plugins on the same agent and causes false alerts.
