This API is used to change the private IP address of a DB instance.

This operation cannot be performed on frozen or abnormal instances.
An in-use IP address cannot be used as the new private IP address of a DB instance.
Changing the private IP address will cause the original database connection address to become invalid. If an EIP has been bound to the DB instance, do not unbind the EIP when the private IP address is being changed.
This operation is not allowed if connection address switchover is enabled.
Currently, only the IPv4 address is supported.
