v1.52.0

⚠ BREAKING CHANGES

• rds: the property 'version' has been changed from string to an engine-specific
  version class; use VersionClass.of() if you need to create a specific version of an engine from a string
• rds: the property ParameterGroupProps.family has been renamed to engine, and its type changed from string to IEngine
• rds: the property engineVersion in IClusterEngine changed from a string to EngineVersion
• rds: the property engineVersion in IInstanceEngine changed from a string to EngineVersion
• rds: the property parameterGroupFamily in IClusterEngine changed from required to optional
• rds: the property parameterGroupFamily in IInstanceEngine changed from required to optional
• rds: the class ClusterParameterGroup has been removed -
  use ParameterGroup instead
• rds: DatabaseProxyProps.secret => DatabaseProxyProps.secrets[]
• apigateway: defaultMethodOptions, defaultCorsPreflightOptions
  and defaultIntegration have been removed from SpecRestApiProps.
  These can be specifed directly in the OpenAPI spec or via addMethod()
  and addResource() APIs.

• rds: the class DatabaseClusterEngine has been replaced with the interface IClusterEngine in the type of DatabaseClusterProps.engine
• rds: the class DatabaseInstanceEngine has been replaced with the interface IInstanceEngine in the type of DatabaseInstanceSourceProps.engine
• rds: DatabaseClusterProps.engineVersion has been removed; instead, create an IClusterEngine with a specific version using the static factory methods in DatabaseClusterEngine
• rds: DatabaseInstanceSourceProps.engineVersion has been removed; instead, create an IInstanceEngine with a specific version using the static factory methods in DatabaseInstanceEngine
• rds: the property majorEngineVersion can no longer be passed when creating an OptionGroup; instead, create an IInstanceEngine with a specific version using the static factory methods in DatabaseInstanceEngine
