SimpleStorageResource does not escape special characters in getURI

[osi]

In spring-cloud-aws-core v2.1.2, the SimpleStorageResource does not properly escape special characters when generating URLs or URIs

The following test fails,

@Test
public void getUri_escapes_characters() throws Exception {
	AmazonS3 s3 = mock(AmazonS3.class);
	when(s3.getRegion()).thenReturn(Region.US_West_2);
	SimpleStorageResource resource =
		new SimpleStorageResource(s3,
								  "bucketName",
								  "some/[objectName]",
								  new SyncTaskExecutor());

	assertThat(resource.getURI())
		.isEqualTo(new URI("https://s3.us-west-2.amazonaws.com/bucketName/some/%5BobjectName%5D"));
	}

It throws,

org.springframework.core.NestedIOException: Invalid URI [https://s3.us-west-2.amazonaws.com/bucketName/some/[objectName]]; nested exception is java.net.URISyntaxException: Illegal character in path at index 51: https://s3.us-west-2.amazonaws.com/bucketName/some/[objectName]
