Modify the configuration of the UDB instance - ResizeUDBInstance

Overview

Modify (upgrade and downgrade) the configuration of the UDB instance, including the configuration of memory and disk. For memory upgrades, there is no need to shut down the instance, other scenarios require shutting down the instance in advance. Two sets of parameters can be configured for the upgrade and downgrade machine: 1. Configure UseSSD and SSDType 2. Configure InstanceType, no need to configure InstanceMode. The priority of the second set of parameters is higher.
