Support to inherit common properties for configuring multiple beans

It's used for configuring multiple beans (spring-projects#15732), we could extract common or use primary properties as parent now.

Take `org.springframework.boot.autoconfigure.data.redis.RedisProperties` for example, given:
```
# primary
spring.data.redis:
  host: 127.0.0.1
  port: 6379

# additional
additional.data.redis:
  port: 6380
```
Then effective properties:
```
additional.data.redis:
  host: 127.0.0.1
  port: 6380
```
should be bound to `additionalRedisProperties`:
```java
	@bean(autowireCandidate = false) // do not back off autoconfigured one
	@ConfigurationProperties(prefix = "additional.data.redis", inheritedPrefix = "spring.data.redis")
	RedisProperties additionalRedisProperties() {
		return new RedisProperties();
	}
```
