Whether HA is supported

Value Description: Supports true and false.

Value Constraint: 1. The HA parameter must be consistent with the specification parameter. 2. Note that the parameter must be in the character string format. When a YAML template is used, quotation marks ('' '') must be added because the true/false are considered as Boolean values in the YAML template.

Suggestion: If the instance flavor name contains the HA parameter, set this parameter to true. Otherwise, set this parameter to false. Please refer to RDS documentation - Obtain the flavor information about a specified instance.
