Ticket 49138 - Increase systemd timout
    
    Bug Description:  We encountered a case where the system timeout
    was too aggresive during encrypted changelog replay. This would
    cause DB corruption as systemd killed us.
    
    Fix Description:  Make the timeout infinite to prevent systemd
    killing us.
