Azure Auto Approval

Approve SSO requests by the Web hook.
Azure function name: ApprovePendingRequestsByWebHook
Using this approval method still requires an Azure function executed by timer in order to keep Keeper connection alive.
KeeperConnectionGuard function executed every 6 hours.
Keeper account in config.json needs to be configured to have Logout Timeout set to 12 hours.

successfully executed once.
