* NET-507 * Fixed server restart changing the node expiration date to the defaults. * Removed expired nodes removal from zombie cleanup routine. * Added a new expired nodes deletion routine which removes expired nodes every hour. * NET-507 suggested changes * Possible fix for zombie nodes upon node deletion from the UI. * Suggested changes implemented for expired nodes deletion go routine. * NET-507 typo fix * typo fix for DeleteNode purge parameter
