Allow usage/configuration of IAM for Minio Client

[SidhNor]

Current implementation has MinioClient initialisation set in stone here:

https://github.com/reportportal/commons-dao/blob/develop/src/main/java/com/epam/ta/reportportal/config/DataStoreConfiguration.java#L49

Would be nice to provide a possibility to configure the client with IamProvider, something like below

    @Bean
    @ConditionalOnExpression("${datastore.type} == 'minio' and ${datastore.minio.auth} == 'iam'")
    public MinioClient minioClient(
        @Value("${datastore.minio.endpoint}") String endpoint,
        @Value("${datastore.minio.region}") String region
    ) throws InvalidPortException, InvalidEndpointException {
        Provider provider = new IamAwsProvider(null, null);

        return MinioClient.builder()
            .endpoint(endpoint)
            .credentialsProvider(provider)
            .build();
    }

Hi, we are going to replace MinioClient with JCloud in version 5.7.4, which would use different providers for different binary stores like AWS S3, Minio, etc.
Example for AWS S3:

        @Bean
	@ConditionalOnProperty(name = "datastore.type", havingValue = "s3")
	public BlobStore s3BlobStore(@Value("${datastore.s3.accessKey}") String accessKey, @Value("${datastore.s3.secretKey}") String secretKey,
			@Value("${datastore.s3.region}") String region) {
		Iterable<Module> modules = ImmutableSet.of(new CustomBucketToRegionModule(region));

		BlobStoreContext blobStoreContext = ContextBuilder.newBuilder("aws-s3")
				.modules(modules)
				.credentials(accessKey, secretKey)
				.buildView(BlobStoreContext.class);

		return blobStoreContext.getBlobStore();

Do you still need ability to allow IamProvider in here?

Hi @IvanKustau
The main purpose is to not use accessKey + secretKey - but rather the AWS IAM capabilities.
Probably this can be achieved via https://github.com/apache/jclouds-labs-aws - but wasn't updated for a while

[SidhNor]

But will definitely require a different config bean along with S3 that does not require access key and secret

Couldn't find any kind of documentation or examples on jclouds-labs.
The only useful thing to make this possible that I've found is https://github.com/hazelcast/hazelcast-jclouds.
Maybe we can use this to make possible IAM role configuration

An implementation can be seen here as well https://github.com/minio/minio-java/blob/304b5b7dc036423d34acfdddd504ceea0098f98a/api/src/main/java/io/minio/credentials/IamAwsProvider.java
