Real HA cluster implementation

[Nuxwin]

Hello ;

Of course, I'm interested to by your feedback here. I'm working also on the HA implementation of ispCP with linux-vserver and heartbeat + ldirectord.

In the future, each ispcp services engine script will be correctly separated and will provides some hooks to allow the changes of the default behavior. Currently, the engine scripts don't allow to change easily the management of unix users.
Sure, you're welcome for any improvement and new idea.
