this enables spring to call the stop mehtods of the beans when management server is shutting down.

We have to explicitly set the HOME variable to the homedir from the user "cloud"
This is because various scripts run by the management server read the HOME variable
and fail when this init script is run manually.
For example the injectkeys.sh script reads the HOME variable
