Description

Camel has a @PropertyInject annotation that works for primitives but it would be nice to support complex objects so that one can write:

@BindToRegistry
public static AmazonS3 minioClient(
        @PropertyInject("minio") MinioConfig config) {

    var endpoint = new AwsClientBuilder.EndpointConfiguration(config.getAddress(), "US_EAST_1");
    var credentials = new BasicAWSCredentials(config.getAccessKey(), config.getSecretKey());
    var credentialsProvider = new AWSStaticCredentialsProvider(credentials);

    return AmazonS3ClientBuilder
        .standard()
        .withEndpointConfiguration(endpoint)
        .withCredentials(credentialsProvider)
        .withPathStyleAccessEnabled(true)
        .build();
}

And have minio interpreted as properties root so that users can define properties like:

minio.address = http://my-minio.com
minio.access-key = ...
minio.secret-key = ...

And receive a MinioConfig object configured from those options as method parameter.

As today it is possible to achieve a similar behaviour using @BeanInject in combination with https://issues.apache.org/jira/browse/CAMEL-14525 but I think it would be nice to support such case too.
